Investigation of non-linear optical properties of CdS/PS polymer nanocomposite synthesized by chemical route

Spin-coated nickel doped cadmium sulfide thin films for third harmonic generation applications

“…It has various industrial applications, such as bulk material [5], nanostructures as nanowires [6], and transparent conducting semiconductor [7][8][9]. Besides, pure and doped CdS have gathered considerable interest in electronic [10] and non-linear optoelectronic devices [11]. The observation of the third-order nonlinear optical phenomenon is fundamental for optical applications like optical limiting devices, all optical switching and computing, optical correlators and phase conjugators [12,13].…”

Effect of γ‐irradiation on optical properties of Eu2O3‐doped polystyrene polymer films

“…The emission peaks of PS are shown in the range 360–410 nm and can be attributed to the formation of luminescence substances containing carboxylate ion. These substances might arise from the reaction of the radical with oxygen yield and consequent depletion of hydrogen atom from the carbon adjacent to the phenyl group of PS under light illumination . The emission peaks are shown in the range of 443–502 nm corresponding to polymer structure.…”

“…The modification of polymer composites by exposure to γ‐irradiation has important applications such as in radiation therapy and for medical implants with high strength, corrosion resistance and good tissue adherence . There have been reports of PS composites synthesized with BaF 2, ZnO, Al 2 O 3, CdS, (NA) 3 Eu(III), (NA) 3 Tb(III), (MOBA) 3 ‐Eu (III) and (FBA) 3 ‐Eu (III) fillers at different concentrations using various techniques and on their optical properties. However, to the best of authors’ knowledge there has been no report on modification of optical properties of PS/Eu 2 O 3 composites induced by γ‐irradiation.…”

Morphology and thermal studies of zinc sulfide and cadmium sulfide nanoparticles in polyvinyl alcohol matrix

“…Hence, they are due to band to band transition [44]. PL is commonly used for band gap, band-to-band investigations and also impurity level detection [45].…”
