Abstract Hexagonal boron nitride (h-BN) containing carbon and hydrogen, BN(C, H), has been prepared by chemical vapour deposition. It shows wide photoluminescence in the range 300–600 nm. The luminescence is mostly bright and white-blue in colour to the naked eye. The peak position and shape of the luminescence spectra are totally different from those reported on BN(C, H) made by heating BN powder in a graphite crucible in the presence of hydrogen in the atmosphere. A study by electron spectroscopy for chemical analysis on BN(C, H) indicates that impurity carbon substitutes for nitrogen atoms in the h-BN crystal. In other words, impurity carbon can be introduced into h-BN as an acceptor.
