Abstract

Optical temperature sensing and plant growth lighting multifunctional applications can be realized by red luminescent materials. In this paper, novel Sm3+ and Sm3+-Mn4+ activated Sr2GdTaO6 (SGTO) red phosphors for plant growth and optical temperature sensing were comprehensively analyzed. The phase, luminescence property and thermal stability of the material were tested. For PL performance, SGTO:0.075Sm3+ exhibits the maximum emission intensity in the range (560–670 nm). The emission range of SGTO:0.075Sm3+ after introducing Mn4+ is mainly dark red light emission in the range from 630 to 750 nm, and the optimum doping
concentration of Mn4+ is determined to be 0.3 %. The emission band of SGTO:0.075Sm3+ and SGTO:0.075Sm3+, 0.003Mn4+ matches the absorption band of the plants. For optical temperature sensing properties, the relative sensitivity (Sr) and absolute sensitivity (Sa) of SGTO:0.075Sm3+, 0.003Mn4+ are 2.94 K
