摘要

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 onthe 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.
