 This study investigates two configurations of carbon vacancy defects in hexagonal boron nitrite using density functional theory calculations to determine their relative stability and formation energy. The results show that while CNVB can easily transform to VNCB in neutral and positive charge states, it is stable when negatively charged. However, neither configuration has suitable fluorescence spectra to reproduce the observed ones, indicating that other carbon related configurations may be the origin of the 1.6 to 2.2 EV emitters.
