Abstract
- Facility agriculture has been widely used around the world due to its effective strategy of increasing the added value of agricultural products. The study of Mn4+ doped oxidized red phosphors has become a prominent area of research aimed at addressing the shortage of red light in agriculture and horticulture. In this work, SrZnAl 10 O 17 far-red phosphors doped with Mn4+ were deliberately designed through a high-temperature solid-state reaction. The crystal structure was determined through Rietveld refinement, and a comprehensive analysis of the photoluminescence properties was conducted. When illuminated with light at either 396 or 552 nm, the SrZnAl 10 O 17 :Mn4+ phosphors displayed a distinct narrow emission band, covering the wavelength range of 600–800 nm, with a peak occurring at 692 nm. Notably, the photoluminescence intensity of these phosphors did not show significant variations under 396 and 552 nm light excitation—a relatively uncommon occurrence in Mn4+-doped red oxide phosphors. Furthermore, the photoluminescence spectra of SrZnAl 10 O 17 :Mn4+ phosphors closely matched the absorption spectra of PFR, suggesting the potential application of these phosphors in agricultural cultivation.
