摘要：

Single crystals of Dy3+-doped YPO4 have been grown from Pb2P2O7 flux and investigated by optical spectroscopy techniques. The energy level scheme of the active ion has been deduced from the low temperature spectra and reproduced by means of a crystal-field calculation. The room temperature absorption spectra have been analysed in the framework of the Judd-Ofelt approach, and the results of this analysis have been applied in a discussion concerning the spectral composition of the visible luminescence.
