nam.mx Antimony su
ulfide (Sb2S3) is an interesting semiconductting chalcogenide m
material of the V–VI ggroup becaause of its high refracctive indexx, well‐
deefined quan
ntum size efffects, phottosensitivityy etc. In the present wo
ork, we reeport the fabrication
n of Sb2S3 thin film
ms are byy cathodic pulse ellectrodepossition from solutions containing Sb(III) chlo
oride and ssodium th
hiosulfate. C
Cyclic voltam
metry experriments werre performeed to evaluaate the ellectrochemical processs. The potentials used for the development of the films were between b
‐0
0.7 –0.75 V vs saturatted Calomel electrode (SCE). Fiilms with th
hickness of 80 to 400 n
nm were deeposited by varying thee pulse duration. Th
he crystallin
ne structure and com
mposition of o the filmss were an
nalyzed to ascertain sttructure and phase pu
urity of the films. The results sh
howed the ffilms were polycrystalline with cryystalline sizee of about 15 nm. M
Morphologiccal analysis of the filmss using Atomic Force M
Microscopy (AFM) reevealed a co
ompact and
d uniform ssurface. Thee optical band gap estiimated frrom the tran
nsmittance and reflectaance data w
was in the raange of 1.7‐1.8 eV, an
nd the filmss were found to be foto
osensitive. R.G Avilez Garcia, C.A Meza, M. Pal, N.R Mathews. (2015) Fab
