In this study, the crystal structure, phase purity, functional group presence, and their bending and stretching vibrations, photoluminescence (PL) spectra, thermoluminescence (TL) spectra, and colour purity was systematically investigated. The phosphor exhibits a strong excitation with the charge transfer band (CTB) of O2? and Sm3+ at 263nm. Under 263nm excitation, the CaSi2O5:Sm3+ phosphor shows characteristic peaks at 595nm and 629nm, which are attributed to the characteristic 4G5/2?6H7/2 and 4G5/2?6H9/2 transitions of the Sm3+ ions, respectively. The doping concentration x = 2mol% is found to be the optimal doping concentration. The CIE coordinates of the optimal concentration phosphor CaSi2O5:2Sm3+ are found to be (0.589, 0.41) in the orange-red region with a colour purity percentage of 96.93%. Judd-Ofelt analysis was also carried out with the photoluminescence emission spectrum, in order to investigate the transition dynamics. Fingerprints were developed on non-porous glass and aluminium foil substrates. The experimental results display that the CaSi2O5:xSm3+ phosphors have a huge potential for practical applications.
