optical band gap meaning in Chinese
光禁带
Examples
- Tin sulfide ( sns ) has an optical band gap of 1 . 3ev , which is close to the optimal band gap 1 . 5ev
Sns的光学直接带隙为1 . 3ev ,接近于太阳能电池材料的最佳禁带宽度1 . 5ev 。 - At the same time , we also found optical band gap decreases and photosensitivity of a - si : h films increases with the increase of substrate temperature
同时，我们也发现伴随着衬底温度升高，光学带隙减少，光敏性增加。 - On the basis of uv - vis transmissive spectra , the sputtered films have absorption peaks toward longer wavelength , and the calculation shows the lower optical band gap
适当的掺杂量可以产生新的吸收峰,增加对长波段光的吸收,提高光催化效率。 - So , the decrease of optical band gap and the increase of photosensitivity of a - si : h films is the result of the decrease of hydrogen content , especially incorporated as polydride
因此， a - si ： h光学带隙的减少以及光敏性的增加是膜中氢含量尤其是以多氢化合物结合的氢含量减少的结果。 - By using the uv - vis spectrophotometer and data processing , we get to know that the carbon nitride films have a wide optical band gap of 4 . 14ev , which is 2 . 2ev lower than the theoratical band gap of 6 . 6 0 . 5ev
通过数据处理，得到了吸收率谱，从而得出光能隙为4 . 14ev 。比理论计算值6 . 4ev 0 . 5小2 . 2ev 。这是因为我们的样品是由非晶组成的。
