Abstract
Phosphate glasses and glass ceramics doped with Er3+ and co-doped with Er3+-Tm3+ are presented in this work. The luminescence properties have been characterized by absorption, excitation and emission spectra. All samples excited by blue light could emit a combination of blue/green/orange/red wavelength giving white light. For Er3+-doped glasses, a self-quenching effect has been obtained and an adjustable tune comes out after crystallization. For co-doped glasses, the red emission at 651Â nm has been enhanced due to the existence of Tm3+, which could be relative to both the overlapped emissions and the energy transfer from Tm3+ to Er3+.
