Abstract
The Judd‐Ofelt (JO) theory was applied to optical‐absorption transitions in Nd+3 : YVO4 to obtain intensity parameters (Ω2=5.88×10−20 cm2; Ω4=4.08×10−20 cm2; Ω6=5.11×10−20 cm2) and the radiative lifetime (152 μs) and quantum efficiency (0.72) of the 4 F 3/2 state. The variations of the absorptions with respect to the optic axis measured for Nd+3 in a uniaxial crystal were taken into account in applying the JO theory. In addition, transition‐matrix elements using new intermediate‐coupling coefficients were obtained and used in the JO fitting procedure.This publication has 17 references indexed in Scilit:
