Key Points

  • To explore how varying argon flow during ammonia borane decomposition affects boron nitride film properties.
  • Utilized atmospheric pressure chemical vapor deposition (AP-CVD) for film growth.
  • Examined the thermal decomposition of ammonia borane under different argon (Ar) flow rates.
  • Analyzed the resulting boron nitride films for fluorescence characteristics.
  • Films exhibited fluorescence intermittency, pointing to defects in the material.
  • Defects were identified as potential single photon emitters for quantum applications.

Abstract

Boron-nitride films grown by AP-CVD after thermal decomposition of ammonia borane under low and high Ar flow show fluorescence intermittency, indicating the presence of defects acting as single photon emitters.
