钴铬铜复合离子掺杂黑色玻璃的制备及光吸收特性研究

摘要

Using sodium borosilicate glasses as matrices,the colored glasses doped with single transition metal ion and the black glass doped with composite transition metal ions were prepared.The transmittance spec-tra of the glass samples were determined.Results showed that,glass samples doped with different transition metal ions absorbed different wavelengths of light,the black glass doped with composite ions of Co,Cr,Cu could completely absorb the sunlight of all wavelengths reaching the ground with absorption rate of more than 99%.%以钠硼硅玻璃为基质，引入过渡金属离子为着色剂制备了单一离子着色玻璃和复合离子掺杂黑色玻璃，测定了各玻璃样品的透射光谱。结果表明，不同过渡金属离子对不同波段的太阳光产生吸收，钴铬铜复合离子掺杂黑色玻璃对到达地表的所有太阳光波段的吸收率可达到99％以上。
