New (Deep)-UV NLO Materials: From Synthesis to Applications

Nonlinear optical (NLO) materials are critical in generating coherent light through frequency conversion, e.g., second harmonic generation (SHG). From the ultraviolet (UV) to the infrared (IR), NLO materials have expanded the range of the electromagnetic spectrum accessible by solid-state lasers. Wavelengths where NLO materials are still needed include the UV (~200 – 400nm) and deep UV (< 200nm). Coherent deep-ultraviolet (DUV) light has a variety of technologically important uses including photolithography, atto-second pulse generation, and in advanced instrument development. Design strategies will be discussed, as well as synthetic methodologies. In addition, the crystal growth, characterization, and structure-property relationships in new UV and DUV NLO materials discovered in our laboratory will be presented. Finally, our crystal growth capabilities and recent crystal growth of functional materials will be described.

Appl. ,Adv.Opt. Mater.,Phys. Rev. B (Appl.),Appl. Phys. Lett.等学术期刊发表论文18篇,担任国际学术期刊Crystals的Guest Editor、Frontiers inChemistry的Topical Editor和Frontiers in Photonics的Review Editor。主要研究方向为微纳米晶多光子发光材料、有机-无机杂化体系、纳米光子学及其在新型光电子器件和生物医学领域的应用。


稀土离子具有丰富的电子能级结构,其光子吸收与发射几乎覆盖了整个紫外-可见-近红外光谱区域,被广泛应用于制备各种发光材料。尽管稀土离子4f壳层内的电子跃迁相对稳定,但掺杂浓度调控的离子间相互作用、声子能量决定的非辐射弛豫和辅助的能量传递、温度促进的非辐射跃迁等都将对稀土离子(对)的发光过程产生不可忽略或本质的影响。最近,基于近红外量子剪裁下转换发光、蓝光到紫外上转换和荧光温度探针发光现象,我们对蓝光激发下Tm3+/Yb3+共掺体系、Ho3+单掺体系和Pr3+/Gd3+共掺体系的发光特性展开了系统的研究,对其中所涉及的掺杂浓度(~0.001-0.3)、声子能量(~370-1050 cm-1)和温度(~30-900 K)(综合)调控的能量传递机制进行了初步的探究,基于样品的稳态-动态光谱学实验数据分析和理论模拟与计算,得出了一系列有指导意义的结论。



Vacuum referred binding energies, electronic structure, and materials properties

Knowledge on the electronic structure of a compound together with its intended and unintended defects are crucial to explain its physical and chemical properties. In this seminar Prof. Dorenbos will show how the empirical models were obtained and their physical relevance.  Particularly, the chemical shift model that provides a method to routinely establish the binding energy in the lanthanide states and the host valence and conduction band will be explained. With knowledge on the VRBE at the CB and VB of compounds one may also use spectroscopic data on 3dq, 4dq, and 5dq transition metals or s2-elements like Tl+, Pb2+, Bi3+ to establish their level locations in the bandgap. At the end of the seminar the relevance for other fields of science like battery potentials, photo-catalytic properties, semi-conductor science, and computational physics will be addressed.

Pieter Dorenbos

 Delft University of Technology, Faculty of Applied Sciences, Mekelweg 15, 2629JB, Delft, The Netherlands

Pieter Dorenbos is head of the section Luminescence Materials and has over 30 years of experience in the field. From the start of his career at TU-Delft in 1988, he has been developing inorganic scintillating materials for detection of ionizing radiation. It has led to various patented and now commercially available new scintillators. Dorenbos developed various models to explain and predict the electronic structure, i.e. the electronic level locations of the lanthanides with respect to the conduction and valence band and with respect to the vacuum level. Those models are widely adopted in the field, and extremely useful to understand and predict luminescence properties. In recognition of his work he received in 2018 the Centennial outstanding achievement award from the Luminescence and Display Materials Division of the Electrochemical  society. Dorenbos has an Hirsch index of 68 and  (co)-authored more than 415 peer reviewed papers in scientific journals that were cited more than 18600 times (situation March 2019).

Functional Metal-Based Nanomaterials from Metallopolymers

Wai-Yeung Wong*

Department of Applied Biology and Chemical Technology, The Hong Kong Polytechnic University, Hung Hom, Hong Kong, P.R. China


Metal-containing polymers represent an important research field due to their combination of unique and intriguing redox, electronic, magnetic, optical, and catalytic properties and their ability to be easily processed and fabricated into thin films, fibers, and other forms. As these metallopolymers can be readily shaped and patterned using various lithographic techniques, they offer a convenient synthetic access to patterned arrays of metal NPs with control of their composition and density per unit area. In the first part of this talk, the recent advances in developing new functional organometallic polyyne polymers as precursors to magnetic metal alloy nanoparticles and their lithographic patterning studies will be presented. These metallated polymers (both main-chain and side-chain polymers) are promising as building blocks in realizing high-density magnetic data storage media where the convenient and rapid patterning of magnetic NPs is highly desirable. The bottom-up synthesis of functional 2D metallopolymers from molecular precursors will also be presented in the second part and the resulting metal-complex nanosheets are shown to find wide applications in optoelectronics.

毛陵玲博士于2018年在美国西北大学获得无机化学专业博士学位,2018至2021年于美国加州大学圣塔芭芭拉分校材料研究院从事博士后研究,主要研究新杂化钙钛矿材料的合成和表征及构效关系和光电器件应用。近年来发表了30篇文章和一项专利授权,其中8篇第一作者论文发表在JACS(5篇为ESI高被引),1篇发表在Chem(封面文章),总引用超过2400次,h-index为19(Google scholar 统计)。2020年入选海外高层次人才计划青年项目,2021年加入南方科技大学化学系,任副教授。

报告内容:有机-无机杂化卤素钙钛矿由于其高效的光电转化效率成为近年来的研究热点。其中研究新型杂化钙钛矿中的构效关系是加强新材料设计和提升器件效率的重要手段。在本次报告中,我们将聚焦一系列新型钙钛矿材料及衍生物的构效关系,包括:1.Dion-Jacobson DJ类型的二维杂化铅碘化物,其结构通式为A'An-1PbnI3n+1 (A'= 3-(aminomethyl)piperidinium (3AMP)或4-(aminomethyl)piperidinium (4AMP),A = methylammonium (MA));2.杂化铅氯、溴化合物;3.杂化二维双钙钛矿材料;4.杂化锰溴化物。在新的DJ体系当中,发现其层间距及无极框架的扭曲程度有所缩小,使带隙系统性地缩小。在杂化铅氯、溴化合物中,体现出宽带发射发白光,其半峰宽与结构的扭曲程度直接相关。在最近的一系列锰溴化合物中,发现通过有针对性的改变有机阳离子的价态,官能团和几何构型,可以直接改变自组装形成的晶体结构中的Mn-Mn距离。并且Mn-Mn距越远,其荧光量子产率越高。我们通过系统性地理解新型金属杂化材料中的结构与其光学性质的关系,为下一代新型光电材料奠定了坚实的基础和提供了新的思路。
