Влияние оксида церия в ИАГ-керамике на координаты цветности х, у

Abstract

The luminescence spectrum of YAG-ceramic samples with different amounts of cerium oxide activator was measured. The dependences of the luminescence spectrum reflected from the sample and the chromaticity coordinates x, y, respectively, are revealed. When measuring, due to the different contribution of the blue and yellow components of the spectrum, a dependence on the concentration of the activator is observed, with its increase, mixing occurs in the yellow part of the locus. With special data processing and the allocation of the luminescence spectrum, it can be concluded that the chromaticity coordinates do not depend on the amount of activator. Further studies are needed to confirm the results on other YAG-ceramics samples
