红外光学材料硫化锌衬底上沉积金刚石膜的研究

采用微波等离子体化学气相沉积法，在预镀陶瓷过渡层的硫化锌衬底上沉积金刚石膜。在以前的实验中，我们发现在陶瓷过渡层上沉积金刚石膜极其困难，但采用金刚石诱导形核方法后，我们已经在过渡层／硫化锌试样表面获得了很小面积（约1mm宽的环状区域）的金刚石形核。本文对前期的诱导形核工作进行了一定改进，目前已经使形核生长范围大大增加，沉积面积超过原来10倍。此外，本文对金刚石／过渡层／硫化锌试样的红外透过特性以及金刚石膜质量等进行了评价。

A study of diamond films depositing on multi-spectra ZnS

A ceramic interlayer suitable for diamond film deposition on multi-spectra ZnS substrate was prepared by electron beam evaporation.Diamond film deposition was conducted using microwave CVD method.It was found that diamond nucleation on the ceramic interlayer was extremely difficult.However,an induced nucleation technique was introduced,and diamond nucleation in a small area was obtained(a ring about 1mm in width).In the present investigation,a new study has been carried out to improve the effect of induced nucleation and the much more nucleation area has been obtained,which is more than ten times compared to the former.The quality of diamond film was presented by Raman spectrum.Furthermore IR spectrum of the diamond/interlayer/ZnS sample was displayed.
