Abstract : Photoluminescence properties of cadmium lead boro aluminium fluoride (CdPbBAlF) glasses doped with Sm3+ and Dy3+ ions as a function of various doping concentrations have been synthesized by melt quenching technique. Moreover, the spectroscopic properties of the prepared glasses have been studied by Fourier transform infrared spectroscopy (FTIR), optical absorption analysis, photoluminescence excitation (PLE) and Photoluminescence (PL) analysis. The emission spectra of Sm3+: CdPbBAlF glasses have shown an intense orange-red emission and Dy3+: CdPbBAlF glasses exhibited yellow emission with the excitation at 402 nm and 385 nm respectively. The luminescence quenching behavior of the prepared glasses as a function of the doping molar concentration of Sm3+ and Dy3+ ions was analyzed, which could be useful for optimizing the potential composition towards the novel optical applications. Energy level diagram representing the emission lines and decay curves of the prominent emission transitions of the glasses have been presented.
