Photoluminescence properties of modified chemical bath deposited Copper Oxide thin film

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.
