In-based halide perovskites have attracted a lot of attention because their unique broadband emission properties. Herein, series hybrid (H2MP)2InCl7·H2O (1), (H2EP)2InCl7·H2O (2), (H2MP)2InBr7·H2O (3), and (H2EP)2InBr7·H2O (4) were synthesized under the control halogen ions organic cations. 1, 2, 4 exhibit obvious photoluminescence properties with peaks at 392, 442, 652 nm, respectively. The effects different components on crystal structure are discussed by calculating structural distortion [InX6]3– octahedron. 1 significantly improved after Sb3+ doping PLQY values 57.12 41.53%. Finally, white LED was successfully fabricated two doped compounds coated onto 365 nm blue chip.

Novel and covert fluorescence is quite desirable for fluorescent anticounterfeiting application. Here, Cs2InCl5·H2O/Sb Cs2NaInCl6/Sb with high photoluminescence quantum yields (PLQYs) of 99.61 99.9%, respectively, were achieved. Considering the excellent optical performances together similarity two crystal structures, we tried to realize structure transition from by an ion-exchange method. It was well done just adding NaCl precursor different concentrations in product. Interestingly, a gradual color change yellow orange, warm white, cool blue achieved process transition. The energy-transfer dynamic models Cs2InCl5·H2O/Sb, white product, identified. chemical reaction UV properties made it possible application double-modal highly decreased possibility being cracked copied. Especially, when salt daily cooking used replace NaCl, similar phenomenon happened as that 99.9% precursor, which easy be applicated. combination verifications provides levels security unbreakable encryption. results demonstrate promising
