Abstract
We consider the influence of Li, Na, and K metal dopants on the luminescent characteristics of Y2.97Ce0.03Al5O12 powders. It is shown that the photoluminescence intensity of yttrium aluminum garnet under excitation with blue light with a wavelength of 460 nm decreases with an increase of the content of these metals. The largest effect is observed for Li, the addition of which in amount of 0.05 wt.% leads to a decrease of intensity by 45%. The addition of the indicated metals does not influence the microstructure and the phase composition of the powders.
