Potential Applications

The photophysical properties of the confined dye inside the γ-CD in presence of Au nanoparticles have been studied by steady state and time resolved spectroscopy. It is found that the photoluminescence quenching of C480 dye increases from 26% to 49% due to confinement of dye inside γ-CD. The designing of such new optical based materials having coumarin 480 dye inside the γ-CD in presence of Au nanoparticles may have potential applications for light harvesting system.

Materials Used

In this work, time-resolved thermal lens and beam deflection methods were applied to determine the thermo-optical properties of Er3+ doped sulfophosphate glass in which different concentrations of Titanium dioxide (TiO2) nanoparticles (NPs) were embedded. Thermal diffusivity (D), thermal conductivity (κ), and the temperature coefficient of the optical path length (ds/dT) were determined as a function of NPs concentrations. Moreover, the growth of TiO2 NPs inside the amorphous glass matrix was evidenced by Transmission Electron Microscopy (TEM) images as well as through optical effects such as refractive index change of the glass. The outcomes indicated relatively high values for D and κ as well as a low ds/dT as required for most optical components used for laser media. The addition of TiO2 NPs with concentration of dopants up to 0.6 mol% improved the optical properties of the glass samples but did not affect its thermal properties. The results indicate that the enhanced optical and thermal performance of the proposed co-doped glass fits the quality standards for materials used in photonic devices.
