Abstract

In the presented work, the tellurite glasses TeO-WO-ZnO doped with Tm and Ho ions were prepared by the same glass forming method. X-ray diffraction (XRD) and differential thermal analysis (DTA) techniques were used to study the effects of the forming technology on the thermal and structural properties of the fabricated glasses. After controlled crystallization of investigated glasses, the emission in the VIS- and NIR range was determined. The effect of silver doping on emission intensity was investigated. The value of the activation energy of the glass crystallization process was determined, while the E value for pure TeO glass was much lower than for tellurite glasses TeO-WO-ZnO.

摘要

在本研究工作中，采用相同的玻璃形成方法制备了掺杂Tm和Ho离子的碲酸盐玻璃TeO-WO-ZnO。利用X射线衍射（XRD）和差示热分析（DTA）技术研究了成型工艺对所制备玻璃的热性能和结构性能的影响。对所研究的玻璃进行受控晶化后，测定了其在可见光和近红外范围内的发射情况。研究了银掺杂对发射强度的影响。测定了玻璃晶化过程的活化能值，而纯TeO玻璃的E值远低于碲酸盐玻璃TeO-WO-ZnO的E值。
