Optical and structural investigation of ZnO@ZnS core–shell nanostructures

“…The photoluminescence (PL) spectrum of the ZnO exhibits two excitonic peaks [6], one in the UV region and other at visible region [7,8]. The broad emission band in the visible region (420 nme750 nm) is attributed to deep level defects in ZnO [9,10].…”

ZnO nanoflowers: Novel biogenic synthesis and enhanced photocatalytic activity

“…ZnO nanoparticles are expected to increase the gas sensing and photon-to-electron conversion efficiency due to quantum confinement effect and large surface area [17]. These nanoparticles are used in biosensors [18], optical devices [19], solar cells [20] and photocatalysis [21]. Photocatalysis is an advance oxidation process (AOP) in which a semiconductor material absorbs light of suitable wavelength and help in generation of active species proficient of removing organic pollutants [22].…”

Facile synthesis of thermally reduced graphene oxide-sepiolite nanohybrid via intercalation and thermal reduction method

“…4 might be decreased due to grafting, condensation, stacking and also heating at high temperature (Vinoba et al, 2011a, b;Vengatesan et al, 2012;Kahlout, 2015). Thus, the reduction of pore volume and pore diameter in the hybrid resulted due to the structural construction of clay stacking within the graphene sheets and temperature treatment.…”
