An analysis of the voltage dependence of cathodoluminescence and electron bombardment induced conductivity is given, taking into consideration the surface recombination and diffusion processes. The diffusion equation of DeVore is combined with Young's and Feldman's laws relating to the penetration and energy loss of incident electrons. A good agreement was obtained between the theoretical and experimental brightness vs. voltage curves. By the analysis of this curve the diffusion length L and the surface recombination velocity S may be determined. It was found that L = 0.05-0.15 micron and S = 5 × 103-5×105 cm/sec for several phosphors.
