													    | Abstract  A short-time X-ray-induced long afterglow luminescent material, Ca3(BO3)2:Pr3+, has been developed. The results showed that the phosphor exhibited excellent multiband long afterglow luminescence under X-ray excitation, with the afterglow emission peak primarily located at ultraviolet (270 and 302 nm), green (540 nm), and red (610 nm), corresponding to the 4f5d→3H4, 5, 3P0→3H4, 3P0→3H6 transitions of Pr3+, respectively. More importantly, when X-ray irradiation was applied for 30 s, the intensity of the afterglow after 3 h decay remained 3.9 times that of the background. Even with only 5 s of X-ray irradiation, it can also produce a long afterglow persisting for more than 3 h. In addition, Ca3(BO3)2:Pr3+ exhibited excellent photostimulated performance, producing stable and intense light under periodic irradiation with a 980 nm laser. The thermoluminescence spectra results showed that there were traps with a depth of 0.8 eV, which resulted in excellent long afterglow and photostimulated properties. These results indicated that Ca3(BO3)2:Pr3+ was an excellent X-ray-induced long afterglow luminescent material, which was expected to be used as an in vivo light source for human photodynamic therapy. |
