In recent years, much attention has been given to wide band gap semiconductors for the wide USES in blue and ultraviolet light emitters and detectors.
近几年来，宽禁带半导体材料引起人们的关注，因为这些材料在蓝光及紫外光发光二极管、半导体激光器和紫外光探测器上有重要的应用价值。
The light sources may include laser emitters that combine their outputs into a polychromatic beam.
光源可以包括将它们的输出组合成多色束的激光发射器。
The techniques employed might also help to improve LEDs that produce white light by mixing red, green and blue emitters.
混合的应该是emitters，而不是光线。 其中运用到的技术，可能有助于通过混合红、绿、蓝光源改进发白光的LED。
