Nano-sized La2Ti2O7 oxides were synthesized by sol-gel route. The photocatalytic properties of the Rhodamine B degradation on this photocatalyst were studied as a function of crystallite size, dye concentration, catalyst loading, temperature and inte

It is found that ferroelectric nanoparticles synthesized by the sol-gel technique and milling can become charged during the fabrication. The balance between the concentrations of positively and negatively charged particles depends on the material, th

A Gaussian beam emerging out of a fibre and launched into a dye doped nematic liquid crystal experiences self-waveguiding for appropriate input power in the milliwatt range. This is a consequence of the large thermal non-linearity exhibited by such a

In this paper we report on experiments performed to estimate the non-locality of the photothermal non-linearity in thick dye-doped nematic liquid crystal (DDNLC). We have studied the interaction of two counter-propagating self-focused laser beams par

A thermal (2D+1) spatial optical soliton in a dye doped liquid crystal

It has been possible to excite a spatial soliton in a dye doped liquid crystal confined in a capillary tube. The phenomenon is explained by a pure thermal nonlinear effect due to dye absorption.
