In this work, a series of Zn 1.96– x GeO 4+1/2 x :Mn 0.04 Yb x ( 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 Mn 2+ to Yb 3+ 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.
