专利号:US-10118833-B2 优先权日:2014-10-02 标 题 :Dimensionally focused nanoparticle synthesis methodology 发明人:ROBINSON RICHARD D; HANRATH TOBIAS; WILLIAMSON CURTIS; NEVERS DOUGLAS 权利人:UNIV CORNELL 摘要:A methodology for synthesizing a nanoparticle batch, such as but not limited to a metal chalcogenide nanoparticle batch and further such as but not limited to a metal sulfide nanoparticle batch is predicated upon an expectation and observation that at elevated concentrations of at least one reactant material within a heat-up nanoparticle batch synthesis method, the resulting nucleated batch comprises nanoparticles that may be dimensionally focused to provide a substantially monodisperse nanoparticle batch. The embodied methodology is also applicable to a continuous reactor. The embodied methodology also considers viscosity as a dimensionally focusing result effective variable.
