中文摘要 | phosphors caybo4:re3+ (re = eu, gd, tb, ce) were synthesized with the method of solid-state reaction at high temperature, and their vacuum ultraviolet (vuv)-visible luminescent properties in vuv-visible region were studied at 20 k. in caybo4, it is confirmed that there are two types of lattice sites that can be substituted by rare-earth ions. the host excitation and emission peaks of undoped caybo4 are very weak, which locate at about 175 and 350-360nm, respectively. the existence of gd3+ can efficiently enhance the utilization of host absorption energy and result in a strong emission line at 314 nm. in caybo4, eu3+ has typical red emission with the strongest peak at 610 nm; tb3+ shows characteristic green emission, of which the maximum emission peak is located at 542 nm. the charge transfer band of caybo4:eu3+ was observed at 228 nm; the co-doping of gd3+ and eu3+ can obviously sensitize the red emission of eu3+. the fluorescent spectra of caybo4:ce3+ is very weak due to photoionization; the co-addition of ce3+-tb3+ can obviously quench the luminescence of tb3+. |
