成功地开发了一种光转换材料LiBaPO4:Eu2+， Pr3+，作为硅太阳能电池的太阳光谱转换器。系统地研究了从3k到室温的光致发光激发和发射光谱、寿命和能量传递机理。结果表明，Eu2+离子吸收并将UV-Vis光子的能量传递给Pr3+离子，Pr3+离子在950 ~ 1060 nm之间表现出强烈的近红外（NIR）发射，与Si太阳能电池的最大光谱响应相匹配。我们相信这种近红外发光荧光粉可能为设计先进的UV-Vis-to-NIR荧光粉开辟了一条新的途径，在太阳光谱转换器中具有广阔的应用前景。
A light conversion material LiBaPO4:Eu2+, Pr3+ is successfully developed as a solar spectral converter for Si solar cells. The photoluminescence excitation and emission spectra from 3 K to room temperature, the lifetime and energy transfer mechanism are all systematically investigated. The results show that Eu2+ ions absorb and transfer the energy of UV-Vis photons to Pr3+ ions, which exhibit an intense near-infrared (NIR) emission between 950–1060 nm, matching well with the maximum spectral response of Si solar cells. We believe that this NIR emitting phosphor may open a new route to design advanced UV-Vis-to-NIR phosphors, with promising applications for solar spectral convertors.
