Abstract

A numerical model of Tm<sup>3+</sup>-Tb<sup>3+</sup>-Eu<sup>3+</sup>-co-doped system for white light generation is presented in this paper. The energy level, electron transition process and rate and power propagating equations are proposed to calculate fluorescence intensity of the system pumped by 359 nm laser. The numerical results reveal that our theoretical result is in good agreement with experimental result in literature. Optimal active ion concentrations are proposed for the system to emit red, blue and green lights which are mixed to generate white light for display and lighting system.
