Effective refractive index of drying droplet of water fullerene suspension
Laser light scattering by a drying droplet of water fullerene suspension several micrometers in size was studied. Two light wavelengths were used. The evolution of refractive index and radius of the droplet was investigated. Resonant scattering was identified and analyzed. Some conclusions were drawn on the microscopic properties of the suspension. Supplementing measurements of samples obtained...
متن کاملRefractive index investigations of nanoparticles dispersed in water
The refractive index of nanoparticles dispersed in water is measured, using the total internal reflection method. The critical angle is determined by the disappearance of diffraction orders from a metal grating. The investigated nanoparticles are titanium dioxide (anatase phase), (35 nm diameter), zinc oxide, (<50 nm diameter), zirconium dioxide, (<100 nm diameter). The refractive index is meas...
متن کاملStudying Focusing Properties of Graded Index Photonic Crystals Made of Material with Different Refractive Index
In this paper we investigate focusing properties of graded index (GRIN) photonic crystal (PC) structures which are composed of different materials with different refractive indices. GRIN PC structure is constructed from air holes in dielectric background. The holes radii are varied in the normal direction to the propagation in such a way that a parabolic effective refractive index is produced. ...

متن کاملAN157 Refractive Index Selection
Laser diffraction is one of the most widely used methods for particle size analysis of micron and submicron size powders and dispersions. It is quick and easy and provides very consistent, repeatable information. Since these instruments use scattered light intensity to determine particle size, knowledge of the optical properties, specifically the complex refractive index of the material being a...
