A series of high quality ZnWO4:Tm3+ single crystals were grown with Czochralski method. The concentrations of thulium ions were 0.1, 0.3, 0.5, 0.7 and 1.0 mol%, respectively. When ZnWO4:Tm3+ single crystals were excited by 807 nm laser, the up-conversion luminescence peaks at 486 and 695 nm which corresponded to transitions 1G4-->3H6 and 3F3-->3 H6, respectively, were detected. The intensity of 695 nm luminescence varied with the pump power in a double logarithmic relation whose indexes were 0.8 and 1.1 orders, respectively.
采用提拉法生长了一系列高质量的ZnWO4:Tm3+单晶。铥离子的浓度分别为0.1、0.3、0.5、0.7和1.0 mol%。当用807 nm激光激发ZnWO4:Tm3+单晶时，检测到分别对应于1G4-->3H6和3F3-->3H6跃迁的486和695 nm处的上转换发光峰。695 nm发光强度与泵浦功率呈双对数关系变化，其指数分别为0.8和1.1阶。
