Abstract:Evaluation of the defect levels in low-dimensional materials is an important aspect of quantum science. In this article, we report a facile synthesis method of hexagonal boron nitride (h-BN) and evaluate the defects and their light emission characteristics.The thermal annealing procedure is optimized to obtain clean h-BN. The UV-Vis spectroscopy shows the optical energy gap of 5.28 eV which is comparable to the reported energy gap for exfoliated, clean h-BN samples. The optimized synthesis route of h-BN 1 has … Show more
