B2CN compounds were synthesized from the mixture of turbostratic B2CN precursor and Cu or Ca3B2N4 catalysts at pressure of 5.5GPa and temperature of 1600℃ for 15min. We obtained two kinds of B2CN crystals with hexagonal and orthorhombic structures exhibiting different morphologies. The photoluminescence measurements indicated that orthorhombic B2CN crystal has similar photoluminescence property to GaN being an important blue light-emitting material.
