Phosphate glasses containing different additives of cadmium, zinc, borate, and copper oxides have prepared through melt annealing technique. Copper oxide introduced as a fixed dopant of 0.01 mole and the borate units intercalated the glass network at the expense of cadmium ions. Raman spectra of the studied glasses show the vibration of phosphate units in Q2, Q1, and Q0. The optical transmittance and the optical parameters such as optical band gap, refractive index, and dielectric constant were investigated and recorded as a function of borate units. Density measurements were examined and found to decrease as the borate units increase. The dynamic parameters such as damping ratio and natural frequency of the presented samples were investigated.

研究含硼酸盐的磷酸盐玻璃的一些结构,光学和阻尼特性

含镉,锌,硼酸的不同添加剂的磷酸盐玻璃和铜的氧化物已经通过熔融退火技术制备。作为0.01摩尔固定掺杂剂引入的氧化铜和硼酸盐单元以镉离子为代价插入玻璃网络。研究玻璃的拉曼光谱显示Q 2,Q 1和Q 0中的磷酸酯单元振动。研究并记录了光学透射率和光学参数(例如,带隙,折射率和介电常数)与硼酸盐单位的关系。检查密度测量结果,发现其随着硼酸盐单位的增加而降低。研究了样品的动力学参数,如阻尼比和固有频率。
