METHOD FOR TREATING THE SURFACE OF A II-VI-GROUP COMPOUND-BASED SEMICONDUCTOR NANOCRYSTAL CAPABLE OF IMPROVING THE LIGHT EMITTING EFFICIENCY OF A CADMIUM SELENIDE NANOCRYSTAL
METHOD FOR TREATING THE SURFACE OF A II-VI-GROUP COMPOUND-BASED SEMICONDUCTOR NANOCRYSTAL CAPABLE OF IMPROVING THE LIGHT EMITTING EFFICIENCY OF A CADMIUM SELENIDE NANOCRYSTAL
PURPOSE: A method for treating the surface of II-VI-group compound-based semiconductor nanocrystal is provided to reproducibly control the surface state of a cadmium selenide nanocrystal by implementing a tertiary phosphine-primary amine binary surface treatment.;CONSTITUTION: A method for treating the surface of a II-VI-group compound-based semiconductor nanocrystal includes the following: A II-VI-group compound-based semiconductor nanocrystal is dissolved in a solvent to obtain a solution. Tertiary phosphine and primary amine are added in the solution. The II-VI-group compound-based semiconductor nanocrystal is selected from a group including binary compounds, ternary compounds, and quaternary compounds. The binary compounds include CdSe, CdTe, ZnS, ZnSe, and ZnTe. The ternary compounds include CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, CdZnS, CdZnSe, and CdZnTe. The quaternary compounds include CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe, and HgZnSTe.;COPYRIGHT KIPO 2012
