摘　　要：采用丘克拉斯基法生长出一系列ZnWO4:Tm3 + 单晶 ,Tm3 + 浓度x =0 1 ,0 3,0 5 ,0 7和 1 0mol%。用 80 7nmLD激发 ,观察到 4 86和 6 95nm的上转换发光 ,分别相应于 1 G4→ 3 H6和3 F3 → 3 H6的跃迁 ,发光强度与泵浦光功率成双对数关系 ,其指数分别为 0 8和 1 1次方关系。A series of high quality ZnWO 4:Tm 3+ 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 ZnWO 4: Tm 3+ single crystals were excited by 807 nm laser, the up conversion luminescence peaks at 486 and 695 nm which corresponded to transitions  1G 4→ 3H 6 and 3F 3→ 3H 6,  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.
