Study of Optical Property of Ce3+ doped Li15(SO4)5F4Cl Unique Halosulphate Phosphor

For the first time in phosphor history, a remarkable series of Ce3+ ion-doped Lithium Fluoride Chloride Sulphate i.e., Li15(SO4)5F4Cl alkaline halo sulphate phosphors are made using a wet chemical process. Using X-ray diffraction (XRD) tests, the phase creation and concentration were ascertained. Additionally, Fourier Transform Infrared (FTIR) spectroscopy was used which makes it possible to identify the chemical linkages successfully and browsing electron microscopy was tested for surface investigations (SEM). When the photoluminescence (PL) characteristics of the as-prepared phosphors were examined, it was discovered that the Ce3+ ions in these hosts produced a broad Ultra-Violet (UV) emission. These could be used for scintillation and as potential UV lamp phosphors.
