Abstract
BCNO phosphor has been paid much attention due to their unique physical, electronic and optical properties. Here we have successfully obtained BCNO nano-particle phosphor by microwave treating from boric acid, urea, and glucose at low temperatures and in short reaction time. Glucose decomposed into graphene quantum dots (GQDs), which facilitated the formation of hexagonal boron nitride (h-BN). Through our method, GQDs domains were uniformly incorporated into h-BN, leading to the formation of BCNO and decrease of bandgap. BCNO demonstrated excellent performance in light emitting diodes (LEDs) with green and blue light. We envision that this BCNO phosphor will enable the next generation blue and green LED devices due to the easiness of large scale fabrication at an economic cost.
