摘要：在氟化锌(ZnF₂)或氟化锆(ZrF₄)，氟化铅(PbF₄)等基质材料中加入不等量的Er³⁺及微量Yb³⁺离子，在特定的条件下制作成能量上转换材料。样品在980 nm的红外光激发下发出较强的多波段的可见光，且肉眼可见。由实验样品分析了稀土Er³⁺上转换可见光各波段的谱线，给出了能级跃迁机制，并根据稀土Er³⁺摩尔浓度不同的样品其上转换发光强度的不同，分析了掺入稀土的浓度对能量上转换效率的影响。

Abstract：Energy-upconversion meterials were produced by adding Er³⁺ and Yb³⁺ ions to lead fluoride, zirconium fluoride or zinc fluoride under specific conditions.Under the excitation of infrared light at 980 nm, the material samples emit relatively strong multi-band visible light, which comes into view by naked eyes.Based on the experiment, the multi-band visible spectral lines of Er³⁺ were analyzed, the energy level transition mechanism was given, and the effect of rare earth doping concentration on the energy upconversion efficiency was analyzed, according to the different upconversion light emitting intensity from samples with different Er³⁺ mol concentrations.

Key words：Energy up-conversion;Er³⁺;Yb³⁺;Fluorescence spectrum
