phosphorLaNbO4down-conversionThe solid-state reaction method was used for obtaining LaNbO4 (LNO) samples doped with Pr3+ (1 mol%). Results of XRD and Rietveld refinement confirms that the LNO phase remains in the doped sample without the formation of secondary phases. Down-conversion studies...
Efficient energy transfer was demonstrated in the SrF2: Eu2+, Pr3+phosphor synthesized by the co-precipitation method. Results obtained with X-ray diffraction (XRD), scanning electron microscopy (SEM), x-ray spectroscopy (XPS), photoluminescence (PL) and decay curves proposed the UV-Vis energy ...

Heating the CaSO4:Eu3+,Pr3+ phosphor for 2 h under an Ar-H2 (5%) atmosphere at 1050u00b0C gave CaO as by-product in addition to CaS. The resulting phosphor exhibited red-emission at 646 nm originating from Eu2+ ions upon visible light irradiation, and gave some afterglow after ...
Currently, the development of efficient red-emitting persistent phosphor is still an ongoing challenge. Herein, a novel red-emitting LPL phosphor Ca3Ti2O7:Pr3+ is successfully prepared by a high-temperature solid-state method. XRD Rietve... Bo,Wang,Hang,... - 《Inorganic Chemistry》 被引量...
Polycrystalline CaTa2O6:Pr3+ phosphor is prepared by calcination of a stoichiometric mixture of Ta2O5 and CaCO3 plus a 0.5 mol% PrCl3 dopant level (1200 °C, 4 h).doi:10.1002/chin.201414007L. L. NotoDep. Phys., Univ. Free State, Bloemfontein 9300, S. Afr.M. L. Chithambo...
Up-conversion (UC) phosphor converting visible light into ultraviolet C light (UVC) has potential application in many fields. However, the lower energy conversion efficiency limits its practical application. Here, we proven that the synthesized Li 2 SrSiO 4 :Pr 3+ phosphor is an efficient UV ...
The particle size of ~ 62.54 nm was determined by high-resolution transmission electron microscopy analysis and scanning electron microscopy confirmed the phosphor's porous nature. The Kubelka–Munk function was used to compute the band gap of the phosphors which is in the range 3.296 to ...
We succeeded in developing a new praseodymium (Pr3+)-doped BaTiO3 phosphor with the addition of Mg, which exhibits a strong red emission, using a high-concentration sol–gel process in which the obtained gel was fired at 1200°C for 2 h. The photoluminescence is due to intra-4f transitions...
