Preparation and Characterization of ZnO: Eu, Mn Luminous Material

Abstract:

Chemical precipitation method was used to prepare phosphors ZnO: Eu²⁺ and Mn²⁺ (urea as a precipitating agent, ZnO as a substrate and Eu, Mn as doping elements). A series of preparations with different composition and sintering temperature were characterized by scanning electron microscope (SEM), thermal gravimetric analysis (TG-DTA), x-ray powder diffraction (XRD) and fluorescence spectrophotometer respectively, and the nano-particle characteristics and luminescence properties of the product were studied in detail. The results showed that the size of the nano-particle was uniform (with a narrow distribution), and the fluorescence mechanism would not change when Eu and Mn were doped in the ZnO matrix to prepare luminescence material, it was a feasible way to reduce the damage to the environment and further to explore the ZnO phosphor technology and the application of light-emitting.change when Eu and Mn were doped in the ZnO matrix to prepare luminescence material, it was a feasible way to reduce the damage to the environment and further to explore the ZnO phosphor technology and the application of light-emitting.
