Optical analysis of RE3+ (RE=Eu, Tb): CdO-PbO-B2O3-AlF3 glasses

In this article, we report on the photoluminescence properties of cadmium lead boro aluminum fluoride (CdPbBAlF) glasses as a function of various doping concentrations of Eu3+ and Tb3+ ions. The emission spectra of Eu3+: CdPbBAlF glasses have shown bright reddish emission at 613 nm (5D0 → 7F2) under the excitation at 395 nm and Tb3+: CdPbBAlF glasses exhibited intense green emission at 545 nm (5D4 → 7F5) with the excitation at 379 nm. The luminescence quenching behavior of the prepared glasses as a function of the doping molar concentration of Eu3+ and Tb3+ 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 at 613 nm, 545 nm of Eu3+ and Tb3+: CdPbBAlF glasses have been presented.
