Synthesis and Spectroscopic Analysis of Ca3Al2Si2O8Cl4:Sm3+ Phosphors for Optical Applications
摘要
A solid-state reaction synthesis method was used to prepare Sm3+ doped Ca3Al2Si2O8Cl4 phosphors. Body centered cubic structure with space group la3d (No. 230) was confirmed by the X-ray diffraction method (XRD). The size and morphology of the synthesized microparticles were determined by scanning electron microscopy (SEM). The elements that are present in the prepared sample have been confirmed by elemental mapping and EDS. The luminescence emission and excitation spectra of Sm3+ doped Ca3Al2Si2O8Cl4 phosphors result in peaks of notable intensity and strength. There is significant emission peak in the orange region at 565, 603, and 652 nm when the matrix is excited at 403 nm due to its 4G5/2
