A Judd-Ofelt analysis is performed to calculate the optical properties of Nd 3+ ions embedded in a fluorozirconate glass matrix. The changes in the Judd-Ofelt parameters were determined as a function of the size of BaCl 2 nanocrystals grown inside the matrix. From these data, the radiative decay rates and the branching ratios of every transition in the energy range from 25.000 cm −1 to the ground state are calculated. This was accomplished for samples containing nanocrystals with average sizes ranging from 10 to 40 nm.
