| Abstract: The Ba2TiP2O9 phosphor was synthesized via the conventional high-temperature solid-state method. The Ba2TiP2O9 phosphor showed high luminance white-light emitting when excited under 254 nm radiation. Furthermore, obvious long-lasting phosphorescence could be observed when the UV excitation source had been removed. XRD and photoluminescence (PL) spectra as well as the luminance decay were used to characterize the synthesized phosphor. The results of XRD indicated that the products obtained under 1 100 ℃ for 3 h had a good crystallization. Both the PL spectra and luminance decay measurement revealed that this kind of phosphors was a new kind of white-light-emitting phosphor. The thermoluminescence properties have also been investigated. The energy level of the 352 K and 493 K TL peaks have also been calculated and found that their energy level values were 0.35 eV and 1.08 eV, respectively. The 352 K TL peak is responsible for the origin of the long-lasting phosphorescence. |
