This present work reports an ecofriendly approach for the synthesis of spherical gold nanoparticles (Au NPs) using aqueous leaf extract of Terminalia arjuna. T. arjuna contains arjunetin, leucoanthocyanidins and hydrolyzable tannins, which are found to be responsible for the bio-reduction of Au NPs. The formed Au NPs were characterized by UV–vis, FTIR, XRD, AFM and TEM analysis. UV–visible spectra of the aqueous medium containing gold nanoparticles showed a surface plasmon resonance peak ...

Development of a novel high optical quality ZnO thin films by PLD for III–V opto-electronic devices
[ PUBLICATION ]
A novel highly transparent intrinsic zinc oxide (ZnO) thin films (without adding any dopants and annealing) were grown by pulsed laser deposition (PLD) technique using Johnson Matthey “specpure”- grade ZnO pellets. The effects of substrate temperatures on zinc oxide thin film growth, optical transmission, absorption, reflection and photoluminescence properties were studied. As well as the feasibility of developing high quality transparent oxide thin films was also studied simultaneously. ...

The present study reports the biological synthesis of silver nanoparticles using crustacean immune molecule β-1, 3 glucan binding protein (β-GBP) purified from the haemolymph of blue swimmer crab Portunus pelagicus. The characterization of synthesized β-GBP based silver nanoparticles (Ppβ-GBP-AgNPs) was made by UV-Vis spectroscopy, XRD, FTIR and TEM analysis. UV-Vis spectra recorded the strong absorbance peak at 420 nm due to its surface plasmon resonance. The XRD analysis revealed the ...

A novel crystal growth method has been established for the growth of single crystal with selective orientation at room temperature. Using volatile solvent, the saturated solution containing the material to be crystallized was taken in an ampoule and allowed to crystallize by slow solvent evaporation assisted with a ring heater. The orientation of the growing crystal was imposed by means of a seed fixed at the bottom of the ampoule. By selecting a suitable ring heater voltage and by ...

We have optimised and deposited epitaxial indium zinc oxide (epi-IZO) (In2Zn2O5) thin films on 〈100〉 oriented Si, GaAs and InP by laser-molecular beam epitaxy (L-MBE) technique, i.e., pulsed laser deposition (PLD). Optimised growth conditions have been obtained for the deposition of high quality epi-IZO thin films. To our knowledge, this is the first time that the PLD deposited indium zinc oxide thin films on semiconductor wafers have been applied to semiconductor–insulator–semiconductor ...

A new NLO material, urea doped benzophenone single crystals having different concentrations of urea were grown by slow solvent evaporation technique. The role of urea in benzophenone–ethanol–urea liquid system was analyzed by FTIR and dielectric studies at 1kHz. The observed N–H stretching in addition to benzophenone functional groups absorptions in FTIR spectrum recorded on the grown crystal confirms the doping of urea. Also, the comparison between the finger print regions of ...

Preparation and characterization of ZnO thin films on InP by laser-molecular beam epitaxy technique for solar cells
[ PUBLICATION ]
Highly c-axis oriented ZnO thin films were epitaxially grown on semi-insulating 〈100〉 oriented InP substrates (SI-InP) held at room temperature (RT), 200°C and 300°C by laser molecular beam epitaxy (L-MBE) i.e., pulsed laser deposition. Through X-ray diffraction analysis, the material, the crystalline quality and the epitaxial lattice matching of the film were confirmed. The obtained high intense peak shows that the most preferential orientation was (002), i.e; along the ‘c-axis’. ...

Microtube-Czochralski technique (μT-CZ): a novel way of seeding the melt to grow bulk single crystal
[ PUBLICATION ]
A novel microtube seeding has been proposed in the conventional Czochralski pulling technique to grow a bulk single crystal. The versatility of the technique has been shown by adopting this method for the growth of benzil. Benzil single crystals having hexagonal facets are grown by this technique called the microtube-Czochralski technique (μT-CZ). Due to capillary rise, a fine column of melt was crystallized inside the microtube, which leads to the formation of the single crystal ...
