Abstract:

NaBiF4∶Yb/Er/Mn samples with different concentrations of Mn2+ were fabricated via the solvothermal method. Also, the morphology and crystal phase, the changes of upconversion luminescence(UCL) upon different doping amounts of Mn2+ were investigated. Meanwhile, the mechanism of energy transfer in NaBiF4∶Yb/Er/Mn was also discussed. The results indicate that, for NaBiF4∶Yb/Er, Mn2+ doping does not induce transition from hexagonal to cubic phase, but increases the size of the particles. Meanwhile, the energy transfer processes between Er3+ and Mn2+ can take place in NaBiF4 host, which eventually enhances the red emission to a certain degree. With the increasing of the concentration of Mn2+, the intensity ratio of red to green emission is also increased. In addition, the temperature-dependent UCL spectra of NaBiF4∶Yb/Er/Mn was investigated, and the intensity ratios of red to green emission and 520 nm green emission to 540 nm green emission are generally increased with elevated temperature.
