Cd0.9Co0.1S nanostructures concentration study on the structural and optical properties of SWCNTs/PVA blend

Effect of Ag/CuS nanoparticles loading to enhance linear/nonlinear spectroscopic and electrical characteristics of PVP/PVA blends for flexible optoelectronics

“…The refractive index (n), optical conductivity (σ opt. ), dielectric parameters (real ε r, and imaginary ε i ) and surface/volume energy loss functions (SELF/VELF) were calculated as 4,13,40,41 :…”

“…In recent years, polymeric blend nanocomposites have been given exceptional concerns owing to their contributions to various applications including optoelectronics, photonics, medicine, photovoltaics and entertainment sectors. [1][2][3][4][5][6][7][8] Polymeric blends (PBs) could be attained by mixing two polymers or more with specific ratios to produce new polymeric materials with certain characteristics. [9][10][11][12] Polymeric nanocomposites (PNCs) are prepared by incorporating polymers or polymeric blends with nano fillers to match desired features.…”

Impact of Mn–Ni spinal ferrite nanoparticles on the structural, morphological, surface roughness, and optical parameters of polyvinyl alcohol for optoelectronic applications

“…In the visible region (specifically at l = 600 nm), the n value increases gradually from 1.382 for pure PVA to about The optical conductivity (s opt ) refers to the conductivity coming from free charge carriers, besides the excited charge carriers coming from the incident electromagnetic beam of photons. s opt can be calculated using n and a data as follows, 52 s opt ¼ anc 4p (10) where c (= 3 Â 10 8 m sec À1 ) is the velocity of light.

“…Various efforts have been made to enhance the optical parameters of polymer matrices using different filler materials. 10–15…”

“…Various efforts have been made to enhance the optical parameters of polymer matrices using different filler materials. [10][11][12][13][14][15] Recently, researchers have used ferrite materials as a dopant in polymer matrices to enhance their physical properties. [16][17][18][19][20][21][22][23] Ferrites are compounds synthesized by linking Fe 2 O 3 to one or more additional metallic elements with a formula MFe 2 O 4 , where M is a metal cation like Zn, Mn, Co, Cu, Ba, Sr, Ni, etc.…”
