摘要: Abstract In this work, lead phosphate glasses doubly doped with Tb3+ and Ln3+ (Ln = Eu, Sm) ions were prepared. The excitation emission spectra of lanthanides recorded. luminescent properties containing various concentrations acceptor analyzed. It is observed that luminescence bands corresponding to characteristic transitions rare earth are present on measured under direct Tb3+. From the spectra, Commission Internationale de I'Eclairage (CIE) chromaticity coordinates (x, y) calculated in relation potential application studied systems for white LEDs. Luminescence lifetimes also determined based decay measurements discussed details. general, depend relative optically active dopants.
