A novel optical sensor has been proposed for sensitive determination of bismuth ion basedon immobilization of 4-(4-nitrophenylazo)-1-naphthol on a triacetylcellulose membrane.Chemical binding of bismuth ions in solution with a 4-(4-nitrophenylazo)-1-naphtholimmobilized on the triacetylcelluse surface could be monitored spectrophotometrically. Theoptode shows excellent response over wide concent...

A comprehensive study on the structural, electronic and nonlinear optical (NLO) properties of alumina nanostructures (Al2O3)n with n = 2-5 belonging to the groups III and VI dopants carried out by density functional theory. The NBO charges exhibit dopant atoms caused to the increasing charge transfer and introduces acceptor-donor model for NLO response of alumin...

Superconductivity, an emergence of a macroscopic quantum state, gives rise to unique electromagnetic responses leading perfect shielding magnetic field and zero electrical resistance. In this paper, we propose that superconductors with the space-inversion symmetry breaking host giant nonreciprocal optical phenomena, such as photocurrent generation second harmonic generation. The show divergent ...
