Structural characterization and photoluminescence properties of zinc oxide nano particles synthesized by chemical route method

Abstract: Nanostructures, crystalline Zinc oxide powder were synthesized by mixing Zinc chloride (0.04M) and sodium hydroxide (0.08M) using chemical route method. 0.001M molar concentrations of TEA (Tri ethanolamine) in aqueous solution used to the growing reaction solution. The powder samples are annealed at 190 C. The experimental results indicate a successful growth of Zinc oxide in solid form which is not observed ever before. XRD, SEM, TEM and PL were performed to characterize the morphology, growth and optical nat… Show more

“…At this point, a zinc oxide phase (shown by ' þ ') appeared and some of the silica nanoparticles were crystallized to crystobalite form (shown by ' Ã '). Similar peaks are reported in the literature [30,31] and as a result, it can be concluded that a zinc oxide phase was formed in the final products owing to an amorphous pattern or particle size of below $5 nm which cannot be detected by XRD analysis. Using the Scherer equation, the crystallite size of final nanoparticles with maximized surface area was calculated as about 18 nm.…”

“…Taunk et al, aimed to more economical and ecological function in ZnO NPs synthesis by hydrothermal method through using low concentration of (zinc chloride -sodium hydroxide -M tri ethanolamine) and lower thermal treatment temperature. The resulted ZnO NPs had smaller size than previous research (7nm) and absorption in the UV region (235-407 nm) [11].…”

“…In pure ZnO NPs spectrum, the emission broad peak from 400 to 620 nm (blue emission) has been observed in Fig. 8, that is appropriate to surface defect in ZnO [43,44]. It is inferred that the silane surface modification during the growth process could greatly reduce the aggregation and thus increase the effective surface luminescence [45].…”
