Here, we describe a hot-injection synthesis of all-inorganic lead-free Cs<sub>2<\/sub>SnCl<sub>6<\/sub>&nbsp;and Sb<sup>3+<\/sup>&nbsp;doped Cs<sub>2<\/sub>SnCl<sub>6<\/sub>&nbsp;NCs. Cs<sub>2<\/sub>SnCl<sub>6<\/sub>&nbsp;NCs present a blue emission peak at 438 nm, whereas a new broad-band emission peak appears at 615 nm for the Sb<sup>3+<\/sup>&nbsp;doped NCs. Comparative structural and spectral characterizations of Sb<sup>3+<\/sup>&nbsp;doped Cs<sub>2<\/sub>SnCl<sub>6<\/sub>&nbsp;NCs with micrometer-sized undoped and Sb<sup>3+<\/sup>&nbsp;doped crystals show that the formation of broad-band orange emission is originted from triplet self-trapped excitons, attributed to the&nbsp;<sup>3<\/sup>P<sub><em>n<\/em><\/sub>\u2013<sup>1<\/sup>S<sub>0<\/sub>&nbsp;transitions (<em>n<\/em>&nbsp;= 0, 1, 2). Our results in Sb<sup>3+<\/sup>&nbsp;doped Cs<sub>2<\/sub>SnCl<sub>6<\/sub>&nbsp;materials provide insights into the machanisms of doping-induced emission centers, and it extends the existing knowledge of optical properties of doped halide NCs for further studies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>J.
