Abstract

The invention provides an Eu < 3 + > / Mn < 4 + > co-doped luminescent material as well as a preparation method and application thereof, and relates to the technical field of luminescent materials. The chemical general formula of the Eu < 3 + > / Mn < 4 + > co-doped luminescent material is Mg2La1-xSb0. 998Mn0. 002O6: xEu < 3 + >, and x is more than or equal to 0.02 and less than or equal to 0.12. The luminescent material provided by the invention can be effectively excited by ultraviolet-near ultraviolet light (230-450 nm) and blue light (460 nm), has an ultra-wideband excitation spectrum (230-580 nm), and can be matched with a near ultraviolet LED chip or a blue light LED chip for use. The luminescent material prepared by the invention can be applied to the field of temperature measurement and control and can also be widely applied to the field of indoor illumination of plants.
