1. a photodetector, comprising:

  • Light-sensitive element (101);

    AndWavelength conversion body (103), is arranged in described light-sensitive element (101) above, concreteBe applied directly to described light-sensitive element (101), described wavelength conversion body (103) is joinedBe set to and convert the light of the first wavelength the light of second wave length to and by the light of described second wave lengthGuide described light-sensitive element (101) into,Described second wave length depends on that the photoresponse of described light-sensitive element (101) has the spy of improvementThe wavelength at place when property, described improvement characteristic is specially than described light-sensitive element (101) in instituteState temperature stability that the photoresponse of the first wavelength increases or the photoresponse value of increase,Wherein said light-sensitive element sensing clash into from described wavelength conversion body with described second wave length theOne light component and directly clash into described light-sensitive element and through described ripple with described second wave lengthThe second light component of long conversion body.
