Luminescence of YAG:Ce Phosphors under Excilamp Irradiation

The paper presents the results of YAG:Ce phosphors luminescence under excitation in 4.0–6.2 eV excitation region by excilamp radiation. It is shown that excitation in the UV region leads to the appearance of bands at 320 and 370 nm. The ratio of the bands at 320, 370, and 560 nm depends on the excit...

Description
Summary:The paper presents the results of YAG:Ce phosphors luminescence under excitation in 4.0–6.2 eV excitation region by excilamp radiation. It is shown that excitation in the UV region leads to the appearance of bands at 320 and 370 nm. The ratio of the bands at 320, 370, and 560 nm depends on the excitation wavelength. It is assumed that the excitation energy is absorbed by nanodefects and transferred to the luminescence centers being in their composition.
