Spectral management and energy‐transfer mechanism of Eu3+‐doped β‐NaGdF4:Yb3+,Er3+ microcrystals

β‐NaGdF:Yb,Er upconversion () microcrystals were prepared by a facile hydrothermal process with the assistance of ethylene diamine tertraacetic acid (). The β‐NaGdF microcrystal morphology was controlled by changing the doses of and NaF. Uniform hexagonal structure can be obtained at the 2 mmol and... Full description

description: β‐NaGdF:Yb,Er upconversion () microcrystals were prepared by a facile hydrothermal process with the assistance of ethylene diamine tertraacetic acid (). The β‐NaGdF microcrystal morphology was controlled by changing the doses of and NaF. Uniform hexagonal structure can be obtained at the 2 mmol and 9‐10 mmol NaF. The emissions of β‐NaGdF:Yb,Er microcrystals were tuned by the variation of Eu doping level (0%‐5%), where the red/green intensity ratio decreased with the Eu concentration increase. It was found on the base of rate equations that with the Eu doping, the energy back transfer process H/S (Er) → I (Er) decreased. In addition, an energy‐transfer process from F (Er) to D (Eu) and a cross relaxation process of H (Er) + D (Eu) → F (Er) + D (Eu) were proposed and verified by rate equations, which dominated the energy‐transfer mechanism between Er and Eu, resulted in the spectra tuning of β‐NaGdF:Yb,Er. The results suggested that the color tuning of β‐NaGdF:Yb,Er,Eu microcrystals would have potential applications in such fields as flat‐panel displays, solid‐state lasers, and photovoltaics.
