Abstract

This paper has found for the first time that in the case of indirect up-conversion sensitization, the proportion of the up- conversion luminous intensity of (formula available in paper) under direct sensitization to 7.50 X 10^-2 (or 1/13.3) under indirect sensitization. This paper has analyzed the physics understanding of the upconversion phenomenon penetratingly. It is found that spontaneous radiation A and multiphoton non-radiate relaxation W_n does act simultaneously.
