Abstract
In present work, the luminescent YAG:Ce ceramics co-doped with variable compositions of rare earth ions (Dy, Tb, Eu) were obtained by uniaxial pressing methods. Comprehensive characterizations of the microstructure and phase composition of YAG ceramics has been carried out. Spectral-luminescent properties of sintered ceramics were investigated under different type of excitations. The temperature dependences of ceramics have been studied. It was revealed that when the YAG ceramics are heated in the temperature range of 0 – 150 C, a slight change in the photoluminescence intensity is observed. The highest temperature resistance is demonstrated by YAG:Ce, Dy, and ceramics, the least YAG:Ce, Tb.
