基本解释

Once the blue-light emission wasobtained, it will not change with the increase of the power density of laser.
且该蓝光发射一旦获得，则其发光强度基本不再随激光功率密度变化而变化。
It is found that the luminous emission of the polymer-carried fluorophores can be strong light, being a blue luminous material.
结果发现，高分子担载荧光体既能辐射强荧光，又是蓝光区发光材料。
A composite of narrow and broad band telescopic images, the view spans about 40 light-years and includes emission from hydrogen in green, sulfur in red, and oxygen in blue hues.
