The spectral selective absorbing theory of rare earth upconversion materials, photonic crystals materials and organic materials is studied. The upconversion materials can absorb the given wave band lights by the method of upconversion theory, the photonic crystals materials can absorb the given wave band lights by the method of instructive films design and the organic materials can absorb the given wave band lights by the method of functional group vibration. The laser stealth possibility and stealthy methods of those spectral selective absorbing materials are analyzed, and the study status is also summarized. The spectral selective laser stealth materials are further researches in promoting laser absorptivity, enhancing practicability and compatibility.
