摘要：In this study, the Ba2La8(SiO4)6O2: xEu3+ red phosphors were prepared by high temperature solid phase method. The phase structure, luminescence characteristics, thermal stability and color coordinates of the samples were analyzed. The results show that the Ba2La8(SiO4)6O2: xEu3+ red phosphors can be excited by ultraviolet or blue light, Under the excitation of 394 nm, the 5D0-7FJ (J = 0,1,2,3,4) transition emission of Eu3+ was observed in the range of 500-750 nm, and the strongest emission peak was located at 703 nm (5D0 -7F4), the optimal doping concentration of Eu3+ is 12 %, and the mechanism of concentration quenching is attributed to the electric quadrupole-quadrupole interaction. The internal quantum efficiency (IQE) of phosphor is 23.82 %. The samples have a high activation energy (0.3193 eV) and good thermal stability in the temperature range of 300 K to 575 K, the color coordinates of all samples are located in the red luminous region. The deep red strong emission peak of Ba2La8(SiO4)6O2: xEu3+ is located at 703 nm, which is consistent with the absorption band of plant photochrome (PFR). The above results indicate that Eu3+-doped Ba2La8(SiO4)6O2 phosphor have potential applications in the field of white light LEDs and plant growth lighting.
