Abstract: We report the synthesis of various III-nitride core and core/shell quantum dots via a colloidal solution process. Organometallic precursors of gallium and aluminum are thermolyzed in a coordinating solvent such as tri-n-octylamine and ammonia gas to generate the GaN, AlN, and AlGaN based nanoparticles. The quantum dots emit with tunable fluorescence throughout the UV and deep-UV region. The optical and NLO properties of these quantum dots (multi-photon excitation) will also be reported.
