Abstract
Luminescence-based detection has attracted widespread interests in oxygen measurement applications due to its great versatility, simplicity, sensitivity and non-invasive measurement. However, the relatively low quantum efficiency prompts a need for developing methods for luminescent enhancement. Plasmonic nanoparticles are known to efficiently enhance emission of the surrounding dyes with a precise inter-distance of nanoparticles and dyes. Here, we reported a novel plasmon-enhanced luminescence system in which the distance between luminescence dyes (PtTFPP) and metal nanoparticles (Au nanospheres, AuNSs) can be tuned by an organic spacer of Resorcinol-Formaldehyde (RF) to investigate the separation dependence on the emission enhancement in the optical oxygen sensors. A maximum enhancement of up to 6.24-fold has been achieved with a 5 nm thick spacer in the PtTFPP-based oxygen sensors. These findings provide a unique platform for exploring the application of metal-enhanced luminescence (MEL) in luminescence-based measurement for oxygen concentration.
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
