In this work, the nonlinear optical properties of Zinc Oxide (ZnO) thin films produced on microscope slide glass substrates at room temperature (RT) using Pulsed Laser Deposition (PLD) method has been presented. PLD system consists of a... more
Good quality bulk size single crystals of inverse soluble lithium sulphate monohydrate (LSMH) have been grown by the modified Sankaranarayanan–Ramasamy (SR) method. A growth rate as high as 3 mm per day has been obtained for LSMH growth... more
Diverse microstructures of monoclinic copper niobate (m-CuNbO 3) were synthesized by solid-state reaction (900 °C, 3–12 h). FESEM data demonstrated that agglomerated clusters grew as an elongated grains which migrated to form web-shaped... more
The nonlinear optical properties of Rh-Pd and Rh-Pt solid-solution alloy nanopar-ticles (NPs) were experimentally investigated by means of the z-scan technique. The open aperture (OA) measurement showed a reverse saturable behavior,... more
Two novel sterically demanding zinc phthalocyanines were synthesized and characterized. Their optical and electrochemical properties were investigated in detail. The emission spectra were recorded in different solvents and the... more

This article demonstrates a series of cyclo-metalated Ir(III) complexes of the type [Ir III (C^N) 2 (N^N)]-(PF 6), where C^N is 2-phenylpyridine, and N^N corresponds to the 4,4′-π-conjugated 2,2′-bipyridine ancillary ligands. All these... more
A novel zinc phthalocyanine derivative [2(3), 9(10), 16(17), 23(24) tetrakis-4-((4-(1,4,5-triphenyl-1Himidazol-2-yl)phenyl)ethynyl)phthalocyanine zinc(II) (PBIPC)] was synthesized by incorporating a triphenyl imidazole moiety at its... more
Nonlinear absorption (NLA) properties and excited state dynamics of a porphyrin and phthalocyanine in the presence of explosive molecules were investigated using the nanosecond Z-scan and femtosecond pump-probe techniques, respectively.... more
Lead halide perovskite nanocrystals (NCs) apart from their overwhelming optoelectronic applications have recently demonstrated promising nonlinear optical (NLO) properties such as strong two-photon absorption cross-sections (∼10 5 GM),... more
We present our experimental and theoretical results on the dispersion studies of non-linear absorption in C solution. Open-aperture Z-scans are performed over the visible region 440–660 nm using an ns OPO. Our results are interpreted... more
