Estimating the term…
A method for patterning materials according to a predetermined, three-dimensional pattern, as well as patterned materials produced by said methods, are provided. A template is prepared comprising a template material, the template having a plurality of pores therein, the plurality of pores comprising a negative of the predetermined, three-dimensional pattern. Colloidal nanocrystals sufficient to fill the pores in the template are also prepared. The pores in the template are filled with the colloidal nanocrystals. A quantum-dot solid is formed from the colloidal nanocrystals within the pores in the template, such that the colloidal nanocrystals are concentrated as close-packed nanocrystals within the pores in the template in the predetermined, three-dimensional pattern. If desired, a conventional solid may be obtained by sintering the close-packed nanocrystals within the pores of the template.
A method for patterning a quantum-dot solid according to a predetermined, three-dimensional pattern, the method comprising the steps of:
A method for patterning a conventional solid according to a predetermined, three-dimensional pattern, the method comprising the steps of:
A three-dimensionally patterned quantum-dot solid, comprising close-packed nanocrystals configured according to a predetermined, three-dimensional pattern, wherein the predetermined, three-dimensional pattern includes regions which are occupied by the close-packed nanocrystals and regions which are not occupied by the close-packed nanocrystals.
