发光带 meaning in English

luminous band

The results showed that both the absorption edge and the pl peak blue - shifted with a decrease of thickness of the films , and that pl intensity and line - width were increased for the films with a smaller thickness
结果发现,在一定薄膜厚度范围内,紫外发光带和光学吸收边均随着薄膜厚度的减小而单调蓝移,且紫外发光强度递增,峰宽变大。
The uv - visible absorption spectrum showed the as - prepared aam templates were transparent within visible light , and the pl curve showed the as - prepared aam templates had a blue pl band in wavelength range of 400nm ~ 60qnm which originated from singly ionized oxygen vacancies
从光致发光特性曲线发现，纳米孔阵列aam在400一600nm之间有一个蓝色发光带，该发光带来源于单离子氧空位。
