摘要：

In this work, a series of Zn1.96-xGeO4+1/2x:Mn0.04Ybx (x = 0.004, 0.04, 0.08 and 0.4) nanophosphors with a tunable morphology and particle size have been prepared by a solvothermal method, showing brilliant near-infrared (NIR) down-conversion performance through the energy transfer from Mn2+ to Yb3+ ions, as well as good solvent dispersability. This makes them suitable for preparing flexible, transparent and luminescent PMMA thin films by the drop-casting method. This approach might open a new avenue for preparing inorganic nanophosphors as well as the corresponding thin films with efficient and easy manipulation.
