摘要

Single-phase InN nanocrystals were synthesized for the first time by a molten salt-based nitridation approach using InCl(3)and LiNH(2)as indium and nitrogen sources, respectively. A molten salt, KCl-LiCl, during nitridation, enabled us to obtain InN nanocrystals at relatively low temperatures ranging from 400 degrees C to 500 degrees C. SEM and HR-TEM measurements coupled with XRD data revealed that InN nanocrystals were formed with average grain sizes of approximately 50-60 nm. Notably, the photoelectrochemical cell fabricated using the InN nanocrystals synthesized at 450 degrees C exhibited a photocurrent response under light irradiation from 400 nm to 880 nm. The precise control of the growth of InN particles using our synthetic approach provides opportunities for developing versatile nitride nanocrystals.
