Paper Abstract

Much strong blue emission has been observed in pentaphosphate non crystals at room temperature, highly doped with Yb3+ and Tm3+ when excited into the Yb3+ 2F7/2 state and the excited states of Tm3+ at 966 nm by laser diode. Energy transfer and back transfer between the two rare earth ions, participation of phonons, and pair induced quenching were demonstrated to be responsible for the upconversion process.
