Abstract
Using the energy transfer parameters deduced from the study on nonexponential luminescence decay of the 4F3/2 level of Nd3+ in YAG at room temperature, it is shown that up to 1.5 at. % Nd, the relative quantum efficiency is reduced by an amount of 18.2C, C being the relative (to Y3+) Nd concentration. It is pointed out that about 20% of this reduction is due to a very effective quenching mechanism inside the nearest-neighbor Nd-ion pairs.This publication has 24 references indexed in Scilit:
