Abstract
We study of spectral characteristics of LiF-UO2 crystals with radiation induced color centers and their stability under action of emission of blue light emitting diode. The luminescence band with bandwidth 500—750 nm was observed upon excitation by blue light emitting diode emission. This indicates the possibility of using LiF crystals, containing uranium and radiation induced color centers (F2, F3+), as a phosphor, that possesses high stability due to special radiation treatment, for white light sources.
