Cavity polaritons around two Er3+ optical transitions are observed in microdisk resonators fabricated from epitaxial Er2O3 on Si(111). Using a pump-probe method, spectral anticrossings and linewidth averaging of the polariton modes are measured in the cavity transmission and luminescence at temperatures above 361 K.

    The influence of Nd3+ doping with different concentration on the luminescence properties of PbWO4 single crystals were investigated by means of the thermo-luminescence, X-ray excited luminescence and photoluminescence spectra. Nd3+ doping has almost the same doping effects as that of La3+ doping...
