LSPR effects in a magnetic–luminescent heterostructure for efficient enhanced luminescence performance

Author affiliations

Abstract

The major challenges faced by magnetic–luminescent bi-functional nanoparticles include poor luminescence intensity and severe magnetic–luminescence quenching. Introduction of an intermediate layer with localized surface plasmon resonance (LSPR) effects in magnetic–luminescent bi-functional nanoparticles plays a major role in solving these challenges. Herein, a fascinating process of plasmonic energy conversion in Fe3O4@WO3@GdF3:Eu3+ heterostructures, which can enhance the luminescence by LSPR effects of WO3, is demonstrated. It is proposed that the LSPR of WO3 is the primary reason for the enhanced luminescence of Fe3O4@GdF3:Eu3+. Moreover, saturation magnetization did not significantly decline on introducing WO3 with LSPR effect. This research conclusion can solve the problems faced by magnetic–luminescent bimodal imaging materials and promote the application of this type of composite materials in tumor therapy and optical confocal microscopy technology.
