美国Cree照明公司已发明一种可以用作太阳盲(对太阳不灵敏的)紫外探测器的AlGaN光电二极管。有许许多多应用,包括查找电力线的故障点和跟踪正在接近的导弹等,都需要探测紫外光,但是标准的硅基光电探测器无法在室外进行测量,因为它们会被太阳 Cree Lighting has invented an AlGaN photodiode that can be used as a solar-blind (sun-insensitive) UV detector. There are many applications that include the detection of power line faults and the tracking of approaching missiles, all of which require the detection of ultraviolet light, but standard silicon-based photodetectors can not be measured outdoors because they can be attacked by the sun
