摘要：

Site-selective laser excitation and luminescence measurements at 15 K of CaMoO4 single crystal doped with Nd3+ and co-doped with Nb5+ charge compensator have been investigated in the spectral region of laser interest involving the (4)F(3/)2. I-4(11/2) transition. A larger than expected number of Nd3+ sites was found and a model to explain this result is presented. A partial diagram of F-4(3/2) and I-4(11/2) levels was constructed from the acquired data and their features are discussed.
