| 中文摘要 | the measurements of vuv-uv photoluminescence emission (pl) and photoluminescence excitation (ple) spectra of rare earth ions activated strontium orthophosphate [sr-3(po4)(2):re, re = ce, sm, eu, tb] are performed. whenever the samples are excited by vuv or uv light, the typical emission of ce-3+,ce- sm3+, eu3+, eu2+ and tb3+ ions can be observed in pl spectra, respectively. the charge transfer bands (ctbs) of sm3+ and eu3+ are found, respectively, peaking at 206 and 230nm. the absorption bands peaking in the region of 150-160 nm are assigned to the host lattice sensitization bands, i.e., the band-to-band transitions of po43- grouping in sr-3(po4)(2). it is speculated that the first f-d transitions of sm3+ (eu3+), and the ctb of tb3+ are, respectively, located around 165 (14 3) and 167 urn by means of vuv-uv ple spectra and relational empirical formula, these f-d transitions or ct bands are included in the bands with the maxima at 150-160 nm, respectively. the valence change of europium from trivalent to divalent in strontium orthophosphate prepared in air is observe by vuv-uv pl and ple spectra. |
