In the present study, we report the synthesis and photoluminescence properties of Copper oxide
(Cu2O) thin film. The Cu2O thin films were synthesized on amorphous glass substrate by using
simple chemical root namely, Modified Chemical Bath Deposition (M-CBD) method at room
temperature. The deposition kinetics played important role to get good quality films with uniform
thickness. The structural, surface morphological, and Photoluminescence properties of the films
were investigated. Crystallization and growth processes obtained micro-spherical shaped grains
of Cu2O due to agglomeration of smaller nano-particles. The room-temperature
photoluminescence study showed a green band at 503nm, 540 nm and a strong red emission at
627 nm.
