Optical Emission Diagnosis of Boron Carbide Synthesized Using Natural Carbon Precursors

Resumo

Boron carbide (B₄C) is a semiconducting material that finds a wide range of industrial and optoelectronic applications because of its unique structural and physical properties. In the present work, boron carbide synthesized from natural precursors such as cotton and aloe vera are subjected to optical emission studies. The morphology of the samples is understood from the field emission scanning electron microscopic images and the optical bandgap from the ultraviolet visible spectrum. The fluorescence emission from the samples is studied using photoluminescence spectra. The CIE plot and power spectrum of fluorescence emission from the samples throw light into the color perception and the spectral distribution of energy revealing the potential of the samples for optoelectronic applications.
