研究了具有高发光量子效率的(Ba, Sr)3MgSi2O8:Eu2+, Mn2+同步发射红蓝双光的荧光材料的光强随温度的变化关系。该荧光材料的同步红蓝光发射光谱由峰值为430 nm的Eu2+的蓝光和660 nm的Mn2+的红光两部分构成，且与植物光合吸收光谱和光合有效光谱相匹配。在293 K~473 K温度范围内，红蓝光均出现了热猝灭，红光峰位随着温度的升高出现蓝移而蓝光的峰位保持不变，反映了Mn2+在基质中多格位占据和Eu2+-Mn2+之间的能量传递过程中电子与声子的相互作用本质。结果有助于加深对 (Ba, Sr)3MgSi2O8荧光材料Eu2+-Mn2+间能量传递机制和热稳定性的理解，对完善和发展生态照明荧光材料和器件具有参考价值。

Dependence of light intensity on temperature is investigated for a dual emission (Ba, Sr)3MgSi2O8:Eu2+, Mn2+ phosphor with a high quantum efficiency. The dual emission spectrum, which matches the photosynthetic absorption spectrum and photosynthetic effective spectrum, is composed of 660 nm-peaked red band and 430 nm-peaked blue band. Thermal quenching of both red and blue band emissions is observed from 293 K to 473 K. The peak position for red exists blue-shift with temperature increasing while that for blue remains unchanged. This phenomenon is most likely associated with a multi-lattice site occupation of Mn2+ and electron-phonon interaction in the host lattice involved in an energy transfer from Eu2+ to Mn2+. The results provide further understanding of energy transfer between Eu2+ and Mn2+ and thermal quenching property of (Ba, Sr)3MgSi2O8 and reference in the application of this phosphor and the fabricated bio-lighting devices.
