Preparationand Characteristics of ZnS-doped Borosilicate Glass(I)
ZnS doped borosilicate glass for nonlinear optical application was prepared by melting and precipitation process. The optical band gap of the precipitated ZnS particles ranged from 3.83 to 3.96 eV compared with the bulk ZnS energy gap of 3.53 eV. This result was interpreted in terms of a quantum confinement effect due to small crystal size. ZnS partilcle size estimated by effective mass approximation ranged from about 39 to 83 $AA$ It increased wtih the increase of heat tratment time and temperature.
Key words: Nonlinear optics, Semiconductor doped glass, ZnS, Borosilicate glass
