Abstract
Europium single doped potassium lutetium tungstate Eu3+:KLu(WO4)2 single crystals have been grown with an active ion doping concentration from 0.5 to 5at% using the top seeded solution growth slow cooling method. The experimental parameters for growing these single crystals have been optimized. Optical absorption and emission cross section were subjected to a detailed spectroscopic study. 58 sublevels were determined. Red visible emission was observed and attributed to the pure electronic transition under UV laser pumping. The CIE coordinates were (0.59,0.35) with 604nm as the dominant wavelength and 84% of purity.
