Luminescence Properties of Cs3Cu2I5 Phosphors Powder with Solid State Method

Year: 2024

Type: article

Abstract: The low-temperature solid-state method is utilized to prepare Cs3Cu2I5 phosphors powder by using the cesium iodide (CsI) and cuprous iodide (CuI) as the raw materials. The phase structures of samples were investigated by using X-ray spectrum and steady-state fluorescence spectrometer. The experimental results show that all of samples were crystallized in the orthorhombic structure with pnma space group at the annealing temperature of 100-400°C. Cs3Cu2I5 phosphors exhibits a strong blue photoluminescence emission with peak at 440nm under excitation at 310nm. With the increase of the annealing temperature in the range of 100-400°C, the photoluminescence quantum yield (PLQY) of Cs3Cu2I5 powder achieved the 79.95%. It is revealed that the prepared Cs3Cu2I5 powder phosphors potentially have the promising application in the blue light emitting materials.
