摘要
PROBLEM TO BE SOLVED: To solve a problem that since in conventional methane gas sensors, the light-emitting peak of light emission spectrum in a 1.6 to 1.7 μm band of YAG: Ce, Er phosphor does not coincide with the absorption wavelength of the methane gas, which is 1,654 nm, the light emission intensity of absorption wavelength of the methane gas is small.SOLUTION: By changing YAG: Ce, Er phosphor to Y(Al, Ga)O: Ce, Erphosphor (YAGaG: Ce, Er phosphor) obtained by substituting the part of the Al in its parent material with Ga, the light emission peak of its light emission spectrum is shifted to the side of 1,654 nm which is the absorption wavelength of the methane gas.
