  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 through 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 Y2O3:Eu3+
microsheet phosphors, a fundamental model for topological luminophor
Y2O3:Eu3++Ag was designed referencing the concepts of topological materials in
order to enhance luminescent performance by composite-luminescence, which
composed of Eu3+centric electroluminescence and surface plasma-enhanced
photoluminescence by Ag. The topological luminophor Y2O3:Eu3++Ag was
successfully synthesized with an asymmetric-discrete Ag nanocrystal topological
structure on the surface just via illumination. Experiment results suggest that
the luminescence performance of topological luminophor Y2O3:Eu3++Ag increased
by about 300% compared with that of Y2O3: Eu3+ phosphors on the same
conditions. The design of a topological luminophor provides a new approach to
further improve the luminescent intensity of phosphors.
