The refractive index (n) and extinction coefficient (k) are related to the interaction between a material and incident light, and are associated with refraction … WebIn this work, Yb3+-sensitized cubic NaYF 4was employed. As illustrated in Figure 1a, Yb3+ions serve as sensitizers harvesting 980 nm excitation energy, while Er3+ions act as representative activators to receive the excitation energy from Yb3+ions upon irradiation.
WebA method for measuring refractive index n of nanosize particles in the visible and near-IR spectral ranges is proposed. The method is based on comparing refractive index n colloid of a colloid solution of nanoparticles in several solvents with refractive indices n solvent of corresponding pure solvents and has an accuracy of ±2 × 10−4. WebThe complex refractive index (dielectric function) of planar CH 3 NH 3 PbI 3 thin films at room temperature is investigated by variable angle spectroscopic ellipsometry and …
