W. Lozano et al., UP-CONVERSION OF INFRARED-TO-VISIBLE LIGHT IN PR3-YB3+ CODOPED FLUOROINDATE GLASS(), Optics communications, 153(4-6), 1998, pp. 271-274
Bright fluorescence in the visible range has been observed in Pr3+ - Y
b3+ doped fluoroindate glass under infrared diode laser irradiation. T
he mechanism which contributes for the upconversion emission is identi
fied and the energy transfer rate between Pr3+ - Yb3+ is Obtained for
different concentrations. (C) 1998 Elsevier Science B.V. All rights re
