摘　　要：采用传统高温熔融法制备了不同玻璃组成的碲钆钨酸盐玻璃(TeO_(2)-Gd_(2)O_(3)-WO_(3)),通过紫外-可见分光光度计研究了碲钆钨酸盐玻璃在分别固定Gd_(2)O_(3)浓度为10 mol%(xTeO_(2)-10Gd_(2)O_(3)-(90-x)WO_(3))和20 mol%(yTeO_(2)-20Gd_(2)O_(3)-(80-x)WO_(3))时,玻璃光学透过性随WO_(3)浓度和熔制温度的依赖关系,并借助光碱度理论进行了解释。结果表明,xTeO_(2)-10Gd_(2)O_(3)-(90-x)WO_(3)玻璃随着玻璃中WO_(3)浓度由0 mol%增加到60 mol%,碲钆钨酸盐玻璃的颜色由浅黄(低于20 mol%)逐渐变为深棕色(40~60 mol%)。另一方面,yTeO_(2)-20Gd_(2)O_(3)-(80-y)WO_(3)(y=40)玻璃随着玻璃熔制温度从1000℃升高到1200℃,碲钆钨酸盐玻璃的颜色从浅黄(低于1050℃),变为深棕色(1100℃)甚至黑色(1200℃)。这种颜色变化是由于随WO_(3)浓度升高,玻璃的光碱度单调增加,导致玻璃截止吸收边红移及玻璃光学透过率降低的共同作用效果。The tellurite-gadolinium-tungstate glasses(TeO_(2)-Gd_(2)O_(3)-WO_(3))with different glass compositions were prepared by the traditional high-temperature melting method,and the color dependence of TeO_(2)-Gd_(2)O_(3)-WO_(3)glasses with the fixed content at 10 mol%(xTeO_(2)-10Gd_(2)O_(3)-(90-x)WO_(3))and 20 mol%(yTeO_(2)-20Gd_(2)O_(3)-(80-x)WO_(3))were evaluated by the optical ultraviolet-visible transmittance,and the color change were explained via the optical basicity of the as-synthesized TeO_(2)-Gd_(2)O_(3)-WO_(3)glasses.It was found that the color of the as-synthesized xTeO_(2)-10Gd_(2)O_(3)-(90-x)WO_(3)glasses gradually changes from light yellow(less than 20 mol%)to dark brown(40~60 mol%)with the increasing content of WO_(3)from 0 to 60 mol%.On the other hand,the color of the as-synthesized yTeO_(2)-20Gd_(2)O_(3)-(80-y)WO_(3)(y=40)glasses changes as a function of melting temperature,from light yellow(below 1050℃)to dark brown(1100℃)or even black(1200℃).This color change results from the combined effect of the red shift of the cut-off absorption edge,that induced by the monotonous increase of the optical basicity,and the decreasing optical transmittance of TeO_(2)-Gd_(2)O_(3)-WO_(3)glasses.
