The crystal structure was refined at room temperature by using single crystal X-ray diffiaction data. Ab- sorption and fluorescence spectra were measured at room temperature. The fluorescence lifetime of KTb(WO4)2 was 114 μs. The specific heat of the KTh(WO4)2 crystal was also measured at room temperature.展开更多
The laser host crystals of KLu(WO4)2(KLuW) with large sizes up to 43 × 35 × 16 mm3 have been grown along, [110], b, and c crystallographic directions, respectively, by the top-seeded solution growth (TSSG) s...The laser host crystals of KLu(WO4)2(KLuW) with large sizes up to 43 × 35 × 16 mm3 have been grown along, [110], b, and c crystallographic directions, respectively, by the top-seeded solution growth (TSSG) slow-cooling method. The macro defects are observed using optical microscopy. The main defects found were cracks, inclusions, growth striations, sector boundaries and twin boundaries. The formation mechanism and approaches to reduce or eliminate the defects have been analyzed.展开更多
