Abstract

As a new candidate in the p-type TCOs group, CuBO₂ has been under research spotlight in very recent years. The present work describes a new cost effective sol-gel technique to synthesize the CuBO₂ nanopowders and structural properties of the same were examined by X-ray powder diffraction studies. The particle size and other morphological information were obtained from field emission scanning electron microscope and transmission electron microscope. The compositional analysis was performed using energy dispersive analysis of X-ray. The transmittance spectra and hence the band gap of the as-synthesized CuBO₂ nanopowder was obtained by a UV-visible near infrared spectrophotometer. The photoluminescence property of this material is reported here for the first time and the material showed efficient photoluminescence with the appearance of a broad peak at 370 nm. The broad band can be deconvoluted and the different peaks were assigned to band to band transition and electron transition in Cu+ ions under the excitation, i.e. 3d⁹4^s1–3d¹⁰.
