Organic\u2013inorganic hybrid metal halides have attracted widespread attention as emerging optoelectronic materials, especially in solid-state lighting, where they can be used as single-component white-light phosphors for white light-emitting diodes. Herein, we have successfully synthesized a zero-dimensional (0D) organic\u2013inorganic hybrid mixed-metal halide (Bmpip)2<\/sub>Pbx<\/em><\/sub>Sn1\u2013x<\/em><\/sub>Br4<\/sub> (0 < x<\/em> < 1, Bmpip+<\/sup> = 1-butyl-1-methyl-piperidinium, C10<\/sub>H22<\/sub>N+<\/sup>) that crystallizes in a monoclinic system in the C<\/em>2\/c<\/em> space group. Pb2+<\/sup> and Sn2+<\/sup> form a four-coordinate seesaw structure separated by organic cations forming a 0D structure. For different excitation wavelengths, (Bmpip)2<\/sub>Pbx<\/em><\/sub>Sn1\u2013x<\/em><\/sub>Br4<\/sub> (0 < x<\/em> < 1) exhibits double-peaked emission at 470 and 670 nm. The emission color of (Bmpip)2<\/sub>Pbx<\/em><\/sub>Sn1\u2013x<\/em><\/sub>Br4<\/sub> can be easily tuned from orange-red to blue by adjusting the Pb\/Sn molar ratio or excitation wavelength. Representatively, (Bmpip)2<\/sub>Pb0.16<\/sub>Sn0.84<\/sub>Br4<\/sub> exhibits approximately white-light emission with high photoluminescence quantum yield up to 39%. Interestingly, the color of (Bmpip)2<\/sub>Pbx<\/em><\/sub>Sn1\u2013x<\/em><\/sub>Br4<\/sub> can also be easily tuned by temperature, promising its potential for application in temperature measurement and indication. Phosphor-converted light-emitting diodes are fabricated by combining (Bmpip)2<\/sub>Pbx<\/em><\/sub>Sn1\u2013x<\/em><\/sub>Br4<\/sub> and 365 nm near-UV LED chips and exhibit high-quality light output.<\/p>\n","protected":false},"excerpt":{"rendered":"
