The peak value position shifting technology for spectral response of multialkali photocathodes is studied. The peak value position of spectral response of multialkali photocathodes can be controlled to meet the needs of different spectral response characteristices of various photoemissives devices. For sounding reflectance of night sky and spectral reflection on some materials, the peak value position of spectral response of multialkali photocathodes can be moved to 0.8 μm by multi information measuring techniques.
