Аннотация: Fe3+ activator is a NIR candidate due to its non-toxicity and low cost. Herein, a NIR phosphor BaZnAl10O17: Fe3+ (BZA: Fe3+) with high external quantum efficiency (EQE = 54.1 %) and excellent thermal stability is synthesized. Various emission spectra can be observed under three different excitation wavelengths, which is attributed Показать полностьюto the occupation of Fe3+ on two octahedral sites and a tetrahedral site. The anti-thermal quenching phenomenon under the excitation wavelength of 340 nm can be attributed to trap-assisted energy compensation, weak electron-phonon coupling and energy transfer between different Fe3+ sites. These sparkling properties indicate application potential in the field of plant lighting.
