Resumen:
Cu nanoparticles obtained by laser ablation of solids in liquids have
been incorporated into chemical bath solutions to synthesize Sb2S3-Cu
nanocomposite thin films. Aqueous colloidal Cu suspensions were added in
different volumes to chemical precursor solutions containing Sb and S
ions to synthesize Sb2S3 matrices with Cu nanoparticles embedded within
them. The obtained films were annealed at 280 & DEG;C in Argon.
Structural properties of the films were analyzed by means of X-Ray
diffraction and Raman spectroscopy, optical properties were determined
by UV-Vis spectroscopy and surface morphology was observed by SEM and
AFM. Presence of Cu nanoparticles into Sb2S3 was corroborated by TEM
measurements. Electrical resistance of the films was studied by
electrochemical impedance spectroscopy. Results are discussed as a
function of annealing and nominal Cu suspension content in the precursor
solutions.& COPY; 2023 The Authors. Published by Elsevier B.V.This is
