Abstract
Photoluminescence enhancement is a topic of interest particularly due to its wide range of applications in bio-imaging, optics, medicine, etc. In this project, our goal is to achieve metal enhanced photoluminescence (MEP) by coating a fluorescent dye onto Soda Lime Glass substrates embedded with silver nanoparticles (Ag NPs). Ag NPs were implanted into substrates using low-energy (70 keV) ion implantation and different ion beam fluences. Optical absorption spectroscopy was used to confirm the existence of Ag NPs in the soda-lime glass. Absorption of Ag NPs was recorded using a UV-Vis Spectrophotometer. The energy of ion implantation is crucial to ions’ penetration depth, a property influencing whether SNPs will enhance or “quench” fluorescence. Dye-coating will be carried out using drop casting and/or spin coating and we will use steady state (excitation, emission) optical spectroscopy to examine the effects of nanoparticles on fluorescence signals of fluorescent dye.
