Abstract :Boron nitride quantum dots insert ignore into journalissuearticles values(BNQDs); are of high interest with their excellent photophsiycal and structural characteristics. BNQDs can be synthesized through hydrothermal synthesis methods with different nitrogen precursors, however, until now the optical properties of BNQDS synthesized with different nitrogen precursors have not been compared in details yet. In this study, BNQDS were synthesized through hydrothermal synthesis methods by using urea, melamine and thiourea as nitrogen precursors and optical properties of BNQDS were compared by comparing emission and excitation characteristics of each BNQD synthesized by different nitrogen precursor. Structural properties of BNQDs were compared through infrared spectrum of each BNQDs. Our results revealed that the change in nitrogen precursor causes significant differences in photophysical and structural properties of BNQDs.
