Characterizing optical and morphological properties of Eriochrome Black T doped polyvinyl alcohol film

“…These applications require materials with high values of the nonlinear refractive index, n , 2 and the third-order nonlinear optical susceptibility, ( ) c , 3 therefore it must be compared with materials already have n 2 and ( ) c 3 high values and for their efficiency to be used in the photon applications viz. polyvinyl chloride doped nickel ions nanoparticles films [35], NiO/xFe 2 O 3 (NPs) [37], titanium nitride/polyvinyl alcohol film [38], Mg doped ZnO nanostructured films [72], MDMO-PPV polymer in tetrahydrofuran solvents [73], TiO 2 thin film [74], ER doped Ni film [75], TB films [76], La 3+ doped tellurite glasses [77], BsubPc-Cl thin films [78] and PMMA/4nEr 2 O 3 [79]. A comparison of these nonlinear parameters values for literature [35,37,38,[72][73][74][75][76][77][78][79] with EBT/PVA film is given in table 1.…”

Also, the value of the nonlinear index of refraction of the sample calculated by the Z-scan method is higher than the values mentioned in the studies [80][81][82][83][84][85][86] that used the same technique, which makes the EBT/PVA film a promising candidate for the use in photon applications especially as an optical limiter for the cw low power laser beam due to the occurrence of the phenomenon of self-defocusing of the laser beam when it passes through the sample, as it was observed in Z-scan experiment.…”
