Abstract

In this paper, the absorption and fluorescent spectrum of Tm³⁺:YVO₄ at room temperature were measured. According to Judd-Ofelt theory, the intensity parameters (Omega) _(lambda )((Omega) ₂ equals 3.166 X 10^-20 cm², (Omega) ₄ equals 1.368 X 10^-20 cm², (Omega) ₆ equals 0.955 X 10^-20 cm²) were worked out. With these values, oscillator strength, spontaneous radiative rate, radiative lifetime, branching ratio and integrated emission cross-section were calculated. The potential application of Tm³⁺:YVO₄ crystal to be a laser material was also discussed.
