A study of the spectroscopic properties of PbFS+ GeO, t WO, vitroceramics doped with Tm'+ and codoped with Yb" and Tm'+ ions upon 680 nm dye laser light excitation is made. The up-conversion emission and excitation spectra have been measured at room temperature. An enhancement of blue emission cente
