| description | Trivalent lanthanides (Ln<sup>3+</sup>) doped bismuth-based inorganic compounds have attracted considerable interest as promising candidates for next-generation inorganic luminescent materials. Here, a series of K<sub>0.3</sub>Bi<sub>0.7</sub>F<sub>2.4</sub> (KBF) nanocrystalline particles with controlled morphology have been synthesized through a low-temperature aqueous-phase precipitation method. Using KBF as the host matrix, Eu<sup>3+</sup>, Tb<sup>3+</sup>, Pr<sup>3+</sup>, Nd<sup>3+</sup>, Sm<sup>3+,</sup> and Dy<sup>3+</sup> ions are introduced to obtain K<sub>0.3</sub>Bi<sub>0.7</sub>F<sub>2.4</sub>:Ln<sup>3+</sup> (KBF:Ln) nanophosphors. The as-prepared KBF:Ln nanophosphors exhibit commendable photoluminescence properties, in which multicolor emissions in a single host lattice can be obtained by doping different Ln<sup>3+</sup> ions when excited by ultraviolet light. Moreover, the morphology and photoluminescence performance of these nanophosphors remain unchanged under different soaking times in water, showing good stability in a humid environment. The proposed simple and rapid synthesis route, low-cost and nontoxic bismuth-based host matrix, and tunable luminescent colors will lead the way to access these KBF:Ln nanophosphors for appealing applications such as white LEDs and optical thermometry. |
