Hydrothermal synthesis and upconversion luminescence of Y2WO6:Yb3+/Er3+ crystals

The Y2WO6:Yb3+/Er3+ crystals were synthesized by the hydrothermal method. The needle-shaped morphology is controllably formed and a number of crystals aggregate as spheres by adding the surfactant of sodium dodecylbenzenesulfonate (SDBS) into the reaction system. The crystal structure, morphology an...

Description
Summary:The Y2WO6:Yb3+/Er3+ crystals were synthesized by the hydrothermal method. The needle-shaped morphology is controllably formed and a number of crystals aggregate as spheres by adding the surfactant of sodium dodecylbenzenesulfonate (SDBS) into the reaction system. The crystal structure, morphology and upconversion luminescence properties of the Y2WO6:Yb3+/Er3+ crystals are conducted on the basis of X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), FTIR and emission spectra. The different emission intensity ratio of the red and green bands is observed for the Y2WO6:Yb3+/Er3+ precursors under different heat treatments. The different intensity ratio are illustrated according to the upconversion mechanism. •The needle-shaped Y2WO6:Yb3+/Er3+ crystals were synthesized by the hydrothermal method.•The morphology was controlled by surfactant SDBS and the relevant mechanism.•The different emission intensity ratios of the red and green bands were observed due to heat treatments.•The distinct luminescence performance was illustrated according to the upconversion mechanism.
