Abstract :
Heavy metal lead germanate glasses doubly doped with Yb3+ and Ln3+ ions (Ln=Er, Tm) were investigated. Up-conversion spectra of Er3+ and Tm3+ were registered under diode-laser excitation of Yb3+. Up-conversion luminescence bands corresponded to 4S3/2→4I15/2 (green) and 4F9/2→4I15/2 (red) transitions of Er3+ as well as 1G4→3H6 (blue) and 3H4→3H6 (NIR) transitions of Tm3+, respectively.
