%X According to electron trapping mechanism, the up conversion luminescence decay model of electron trapping materials CaS:Eu, Sm was proposed, and the related rate equations were established. The solution of rate equations is of 3 order exponential decay form. The up conversion luminescence decay curves of the materials at different temperature were measured and analyzed by nonlinear curve fit method, and the expression of nonlinear curve fit is of the same form as the solution.
