Preparation and Research of Long Afterglow Luminescent Materials

Article Preview

Abstract:

In this paper, sol-gel method at low temperatures, an atmosphere of carbon reduction to replace the use of cyclodextrin system prepared with citric acid as SrAl2O4: Eu2+, Dy3+ Long Afterglow Phosphors nanotechnology. And the use of X-ray diffraction phase identification and fluorescence spectrophotometer with the excitation spectrum of the sample, luminescence spectra and luminescence afterglow to explore research, results show that product with the lower cost has the luminescence properties.
