Ion beam irradiation of ZnS dispersed in PMMA and its photocatalytic application

Ion implantation induced phase transformation and enhanced crystallinity of as deposited copper oxide thin films by pulsed laser deposition

“…The improvement in the crystalline nature of the Cu 2 O phases in the post depositional ion implanted sample can be attributed to ordering of the constituent atoms in the unit cell. A similar enhanced crystalline nature of ZnS nanoparticles has been reported by our research group earlier using low energy ion implantation [23]. The ordering of the atoms in the as deposited samples is likely to be due to transfer of thermal energy arising due to energy loss process via cascade collisions of energetic incident ions with the constituents of the thin film.…”

Структура и свойства облученного электронами ZnS

“…Влияние облучения (гамма лучи, электроны, протоны, нейтроны, ионы) на структуру и структурные параметры ZnS исследовано в [8,18,22]. При облучении электронами с энергией 400 кэВ и флюенсом от 10 17 до 10 19 электрон/см 2 обнаружены новые фазы, идентифицированные как ZnO и ZnO 2 [8].…”

A mechanistic approach for superoxide radicals and singlet oxygen mediated enhanced photocatalytic dye degradation by selenium doped ZnS nanoparticles

“…However, conjugation of polymer-ZnS complex and doping of ZnS nanocrystals with Cu, Ni and Pb was reported to exhibit photocatalytic dye degradation using visible light. 24,25 The other challenge for ZnS NPs has been attributed to its route of synthesis, where chemical precipitation method is recommended to be followed by heat treatment under a nitrogen atmosphere. 26 Here we report the mechanism of photocatalytic dye degradation by Se-doped ZnS nanoparticles.…”
