Profile distribution, Z-scan technique, Optical limiting and thermal lens method studies on Cyanidin-3-O-glucoside chloride.

For the purpose of determining the characteristics of the Cyanidin-3-O-glucoside chloride (COGC) dye, both an FT-IR spectrometer and a UV-Visible spect rometer were employed through the process. At a wavelength of 473 nm, a diode-pumped solid-state (DPSS) laser with an adjustable wavelength was used to quantify the thermally induced optical nonlinearity of the dye in a solvent composed of dimethylformamide. For the purpose of measuring the optical response, the Z-scan technique was utilised.

Electrical, Thermal Lens and Optical Study of Fluorescein Film for Application As Organic Photovoltaic Devices.

This article is devoted to the study of various dielectric and optoelectrical parameters nonlinear optic behaviors, thermal lens and self-diffraction parameters of Fluorescein (FLs) doped polymethyl methacrylate (PMMA) films. The films were prepared with 60 mM. These studies are based on the calculated values of refractive, absorption coefficient, energy gap, extinction coefficient and nonlinear Refraction index .
