β-NaYF₄:Yb³⁺,Er³⁺ microrods were synthesized through hydrothermal methods. Polyethylene glycol with molecular weight of 6000 was used as surfactant. A series of transparent silica gel films with upconversion luminescence property was prepared through sol-gel method; the prepared β-NaYF₄:Yb³⁺,Er³⁺ microrods were used as activator. The silica gel films show strong upconversion emission under excitation of 980-nm laser beam.
