Novel Synthesis of Nanoparticles for Enhancements in Surface Plasmon Coupled Emission

Abstract

We report a novel synthesis route for nanomaterials namely SnSe and SnTe and their application as a simple thin film spacers for achieving 30-45 fold fluorescence enhancements using Surface Plasmon Coupled Emission platform.

Purcell Factor: A Tunable Metric for Plasmon-Coupled Fluorescence Emission Enhancements in Cermet Nanocavities

“…An earlier work utilized a monospacer layer of silver nanoparticles that resulted in fluorescence enhancements superior to conventional SPCE . Prior work from our lab has demonstrated neoteric advancements in SPCE spacer engineering technology with the use of plasma-etched polymer films, noble metal nanoparticles, semiconductor nanoparticles, and low-dimensional carbon allotropes to achieve femtomolar sensitivity and 1000-fold fluorescence enhancements . In a conventional SPCE substrate, the dye–polymer layer is spin-coated onto a 50 nm silver/gold thin film, vapor deposited on a glass slide .…”
