摘    要:用高温合成法合成了CaO-SiO2-B2O3:Pr^3+玻璃,探讨了玻璃的最佳合成温度、玻璃的网络结构并研究了其发光性质。在CaO-SiO2-B2O3:Pr^3+玻璃体系中观察到了Pr^3+的发射光谱。480nm左右的发射峰对应于3P1—3H4跃迁,532nm左右的宽带发射峰对应于3P1—3H5跃迁,546nm左右的宽带发射峰对应于3P1—3H4跃迁,605nm左右的发射峰对应于3P0—3H6跃迁,663nm左右的发射峰对应于3P1—3H3跃迁。研究了掺杂Pr^3+浓度对其发光强度的影响,在该玻璃体系中观察到了浓度猝灭现象。光谱性质表明这种玻璃体系能够把太阳光中的紫外光转换成红光,从而增强红光的发射强度。我们可以利用这些玻璃的发光性质来制备农用转光玻璃。

关 键 词:无机非金属材料  发光性质  稀土激活玻璃
