Abstract

The Ce3+-doped optical quality Li2–2xZn2+x(MoO4)3 single crystals are grown by low-thermal-gradient Czochralski technique. Temperature dependences of PL (photoluminescence) and PLE (photoluminescence excitation) spectra, as well as decay curves are investigated and discussed in 77-300 K range in present article. The study confirmed that ultraviolet (UV) excitation is possible and calculated the CIE chromaticity coordinates, correlated color temperature (CCT), and color rendering index for the crystals.
