Title: Technique for manufacturing small-type ultraviolat sensor
Inventor: JANG YU-BIN
IPC: G01N30/74
Filed: 1999-03-18
Granted: 2001-10-21
Abstract: The present invention uses the characteristic of photosensitive semiconductor ceramic to be reacting under exposure of the ultraviolet rays. For example, add a small amount of Sb5+ into tin dioxide containing Sn4+, that is, SnO2:Sb. According to energy band theory, an electron Sb5+ has more than Sn4+ will be stored in the energy gap or the forbidden band and excited to transit to the conductive band while the material being exposed to the ultraviolet rays. Therefore, the conductivity of SnO2:Sb is increased. The more intensive the ultraviolet rays, the more electrons transiting to the conductive band, which means that the higher the conductivity of the SnO2 ceramic containing antimony, that is, the lower the resistance of tin dioxide. A small-type ultraviolet sensor system can be completed using the characteristic of the material changing its conductivity and resistance under ultraviolet rays, with the peripheral driving power, amplifying and controlling circuit, and the warning system etc. The sensor can detect the intensity of the ultraviolet rays and is a economic and convenient invention.
