Abstract
Magnetically responsive photonic nanochains that have been produced by inducing chaining of uniform magnetic particles during their silica coating process and then allowing additional deposited silica to wrap entire structures. The optical diffraction of these nanochains can be switched on and off by applying magnetic fields.
Claims14
A method of fabricating individually fixed nanochains with a magnetically responsive photonic property comprising:
- coating a plurality of colloidal nanoclusters (CNS) with a layer of silica;
- applying a magnetic field to the plurality of colloidal nanoclusters to assemble the colloidal nanoclusters into photonic chains;
- and
- overcoating the photonic chains with an additional layer of silica.
