Abstract

The optical properties of nanoparticle suspensions in liquids have garnered significant interest recently for their potential use in applications ranging from biomedical imaging to solar energy harvesting. Although previous investigations have provided useful insight into the spectral properties of such suspensions they have been primarily limited to experimental investigation at room temperature. As these suspensions will be used in systems with significant variations in temperature it is important to understand the effects of temperature on the optical properties. Furthermore, the primary spectrometric technique used has considered only transmittance and not the effects of scattering. Here we investigate the effects of temperature on the response of TiO2, Ag, and Au nanoparticle suspensions in water utilizing an integrating sphere and heated cuvette. Additionally the responses are analytically modeled to understand the individual contributions from variations in particle size, volume fraction, and surrounding medium temperature-dependent refractive index changes.
