Red light-emitting phosphors are important to the field of plant lighting. Therefore, it is necessary to further optimize phosphor materials. Herein, we synthesized a sequence of phosphor LaTiSbO6:Mn4+ (LTS:Mn4+). Due to the 2E to 4A2 transition, LTS:Mn4+ phosphors can emit red light in the range of 620–780 nm, with an emission peak at 687 nm. Chemical unit cosubstitution (substituting W6+ - Al3+/W6+ - Ga3+ for Ti4+ - Sb5+) was used as a method to enhance the luminescence properties of LTS:Mn4+. When the substitution ratio of W6+ - Ga3+ and W6...
