  • Direct pyrolysis route to GaN quantum dots
    Patent number: 7488384
    Abstract: Colloidal nanocrystals or “quantum dots” of GaN are directly produced by heating amidogallium dimer, i.e., (Ga2[N(CH3)2]6), in the presence of a functional amine. The GaN quantum dots obtained, which comprise isolated particles 2-3 nm in diameter with a relative broad size distribution (e.g., 20% standard deviation) exhibit strong exciton confinement.
