摘要

Improving luminescent intensity is a significant technical requirement and scientific problem for the luminescent performance of fluorophor materials through the ages. The process control and luminescence performance still limit the developments of luminescent intensity even though it can be improved partly by covering or magnetron sputtering of precious metals on the surface of the fluorophore materials. On the basis of the improvement of luminescence center radiative transition rate by surface plasma resonance and Y ₂ O ₃ :Eu ³⁺ microsheet phosphors, a fundamental model for topological luminophor Y ₂ O ₃ :Eu ³⁺ +Ag was designed through referencing the concepts of topological materials to enhance luminescent performance by composite luminescence, which is composed of Eu ³⁺ centric electroluminescence and surface plasma-enhanced photoluminescence by Ag. The topological luminophor Y ₂ O ₃ :Eu ³⁺ +Ag was successfully synthesized with an asymmetric-discrete Ag nanocrystal topological structure on the surface just via illumination. Experimental results suggest that the luminescence performance of topological luminophor Y ₂ O ₃ :Eu ³⁺ +Ag increased by about 300% compared to that of Y ₂ O ₃ :Eu ³⁺ phosphors in the same conditions. The design of a topological luminophor provides a new approach to further improve the luminescent intensity of phosphors.
