Abstract
Frequency upconversion (UC) experiments were performed with GeO2–PbO glasses, containing silver nanoparticles (NPs), doped with holmium (Ho3+), thulium (Tm3+) and ytterbium (Yb3+) ions. The samples were excited using a continuous-wave diode laser operating at 980nm. The UC intensities and the colors of the samples were controlled by changing the concentrations of the rare-earth ions (REI) and the silver NPs nucleated inside the samples. The colors observed spanned the visible range from the red–yellow to the blue. For a particular combination of silver NPs and REI concentrations it was obtained white light generation corresponding to the CIE coordinates X=0.33 and Y=0.33.
