摘要

A facile pathway for solid-state material luminescence enhancement is proposed here by coating graphene on the surface of luminescent material. Ln(3+) (Yb3+/Er3+)-doped germanium tellurite glasses are prepared by conventional melting and quenching method. With the excitation of 980 nm laser diode, the photo-luminescence intensities of the graphene-coated and uncoated glass samples are measured with different incidence angle of excitation light. When the incidence angle is less than 15 degrees, luminescence enhancement can be observed in the coated samples compared with uncoated one. The insight for the enhancement is also discussed.
