Abstract
Cubic BaLiF3 samples were prepared using a facile surfactant-assisted hydrothermal-microemulsion method. The samples were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The upconversion luminescence (UCL) properties of the Er3+/Tm3+,
Yb3+-codoped BaLiF3 samples were measured under a 980 nm excitation wavelength. Moreover, the effects of varying the concentration of Li+ ions on the luminescence properties of Er3+, Yb3+ codoped BaLiF3 were also investigated.
The Tm3+, Yb3+ codoped BaLiF3 samples displayed multicolor emissions. This behavior can be explained by the pump power dependence of the upconversion emissions and the energy levels diagram.
