| 英文摘要 | Monoclinic phase gd2o3:er3+ nanophosphors were synthesized by the glycine-nitrate process (gnp). green, red and blue/ultraviolet (uv) radiations were observed by 980 nm diode laser excitation. obvious enhancement of the red and blue/uv emissions from the f-4(9/2), h-2(9/2) and (4)g(11/2) levels were observed with increasing er3+ ions doping concentration. power dependence study revealed that two and three photons processes are involved in the upconversion process. emissions excited by an ar+ laser verified the analysis of the upconversion mechanism and indicated that the phonon assisted energy transfer process 4i(11/2) +4i(11/2) - f-4(9/2) + 4i(3/2) becomes prominent and greatly enhances both the red and blue/uv upconversions with increasing er3+ ion doping.
