Luminescence and excitation spectra of YAG:Nd3+ excited by synchrotron radiation

The low-temperature 4f25d→4f3 fast emission of Nd3+ from YAG:Nd3+ has been studied under excitation by synchrotron radiation. Additionally, 4f3→4f3 luminescence of Nd3+ has been observed and assigned to transitions from the 2F(2)5/2 and 4F3/2 multiplet terms. The observed experimental spectra of Nd3+ d-f emission and f-d excitation are well simulated by crystal-field calculations.
