Efficient Near-Infrared Luminescence Based on Double Perovskite Cs₂SnCl₆.

ABSTRACT: Cs₂SnCl₆ double perovskite has attracted wide attention as a promising optoelectronic material because of its better stability and lower toxicity than its lead counterparts. However, pure Cs₂SnCl₆ demonstrates quite poor optical properties, which usually calls for active element doping to realize efficient luminescence. Herein, a facile co-precipitation method was used to synthesize Te⁴⁺ and Er³⁺-co-doped Cs₂SnCl₆ microcrystals. The prepared microcrystals were polyhedral, with a size distribution around 1-3 μm. Highly efficient NIR emissions at 1540 nm and 1562 nm due to Er³⁺ were achieved in doped Cs₂SnCl₆ compounds for the first time. Moreover, the visible luminescence
