摘要：

Infra-red to visible wavelength up-conversion is reported for trivalent holmium ion (Ho3+) doped: YAP, YAG, YLF, SrLaGa3O7 and SrLaGaO4 crystals and ZBLAN glass. The spectra and possible mechanisms of up-conversion are discussed. Changing of the holmium luminescence colour between red and green was observed, after excitation in the 870- to 930-run band. Wavelength-dependent ground state absorption and excited state absorption resonances were investigated and explained. For discussing the up-conversion pathways, we determined the cross-sections for the excited state absorption and for the non-resonant side-band absorption. (C) 2002 Elsevier Science B.V.
