2μm波段发光的氧卤碲酸盐玻璃
摘要：
一种2μm波段发光的氧卤碲酸盐玻璃，该玻璃的成分及摩尔百分比如下：TeO2：40～85，PbO：0～15；PbF2+ZnF2：5～30；ZnO：0～15；GeO2：0～10；Nb2O5：0～10；WO3：0～10；Li2O+Na2O+K2O：3～10；Tm2O3+Ho2O3+Er2O3+Yb2O3：2～7，其中，Tm2O3和Ho2O3至少有一种不为零。该玻璃通过普通熔融法制备。本发明的氧卤碲酸盐玻璃具有红外透过率高、透明无析晶、无气泡条纹、物化性质优良，在2μm波段发光效率高等优点。其制备工艺简单易操作、成本较低。本发明的材料适用于2μm波段中红外激光光学镜头或2μm中红外特种光纤基质材料。
摘要（英）：

The invention relates to a piece of luminous oxyhalide tellurate glass with 2 Mum wave band, the glass compositions and mole percentages are as follows: TeO2: 40-85, PbO: 0-15; PbF2 plus ZnF2: 5-30; ZnO: 0-15; GeO2: 0-10; Nb2O5: 0-10; WO3: 0-10; Li2O plus Na2O plus K2O: 3-10; Tm2O3 plus Ho2O3 plus Er2O3 plus Yb2O3: 2-7, wherein, at least one of the Tm2O3 and the Ho2O3 is not equal to zero. The glass is prepared through a common melting method. The oxyhalide tellurate glass of the invention has the advantages of high infrared transmittance, transparence, no crystallization, no bubbles and stripes, excellent pinhole test, high luminous efficiency at the 2 Mum wave band, etc. The preparation technique is simple, can be operated easily and has lower cost. The materials of the invention are applicable to infrared laser optical lenses at the 2 Mum wave band or infrared special fiber matrix materials at the 2 Mum wave band.
