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

Abstract The low-temperature 4f 2 5d→4f 3 fast emission of Nd 3+ from YAG:Nd 3+ has been studied under excitation by synchrotron radiation. Additionally, 4f 3 →4f 3 luminescence of Nd 3+ has been observed and assigned to transitions from the 2 F(2) 5/2 and 4 F 3/2 multiplet terms. The observed experimental spectra of Nd 3+ d–f emission and f–d excitation are well simulated by crystal-field calculations.
