Abstract
We have investigated the optical and scintillating properties of Lu co-doped Ce:LiYF4 single crystals with various Lu content. In the transmittance and absorption spectra, the absorption peaks at 243Â nm get systematically red shifted in contrast to the peaks at 197 and 200Â nm which get blue shifted with the increase in Lu content. At the same time, emission peaks at 306Â nm and 200Â nm under 295Â nm excitation also get red shifted. The decay time of Ce:Li(Y,Lu)F4 crystals under 295Â nm excitation is found to be faster than that of Ce:LiYF4 and Ce:LiLuF4 crystals. The alpha-peak positions in the pulse-height spectra and decay times of crystals under alpha-ray irradiation are found to vary with the Lu content.
