| 中文摘要 | vacuum ultraviolet excitation spectra of phosphors (la,gd)po4:re3+ (re = eu or tb) and x-ray photoelectron spectra of lapo4 and gdpo4 are investigated. the vacuum ultraviolet excitation intensity of (la,gd)po4:re3+ is enhanced with the increasing of gd3+ content, which implies that gd3+ plays an intermediate role in energy transfer from host absorption band to re3+. when gd3+ is doped into lapo4:eu, charge transfer band (ct band) begins to shift to higher energy region and the overlap degree of ct band and the host absorption band gets greater with more gd3+ doped into lapo4. these results suggest that the dopant (gd3+) gives an important influence on energy transfer efficiency. the top of lapo4 valance band is formed by the 2p level of o2-, whereas that of gdpo4 valance band is formed by the 2p level of o2- and the 4f level of gd3+, showing the differences in band structures between lapo4 and gdpo4. |
