Abstract

Objective: Zinc oxide nanoparticles are assumed to be the foundation for several applications including environmental applications, optical devices, telecommunication, energy storage and so on. Its very crucial to obtain uniform and good quality nanoparticles in their properties point of view.

Materials and Methods: Pure and rare earth material (La) doped ZnO nanoparticles were prepared by co-precipitation route with heating temperature of 200oC and their properties were comparatively studied in this work. The structural properties were carried out by X-Ray diffraction technique and Optical analysis was done by using UV-Vis spectrophotometer.

Results: Structural investigations show that all the crystallites are of hexagonal wurtzite structure with preferred orientation along (101) plane. Further, optical analysis indicates that the average transmittance of the prepared samples is 85 % in visible region of spectrum. Moreover, Energy band gap studies reveal the increase in energy band gap from 3.23eV to 3.24 eV with incorporation of La+3 in ZnO lattice.

Conclusion: These analyses indicate that doping Zinc oxide with lanthanum varies and enhances the properties of prepared thin films.
