Abstract

An orderly array of single-layer silica particles was covered by layer of polymer film, and plasma etching was used to control the exposed area of silica particles. Particles surface was modified by chemical group or physical deposition. CdTe quantum dots with fluorescence were assembled using selective assembly of heterogeneous region. They were fluorescent particles with heterogeneous asymmetric function. Using this method, further the modification of functional groups or particles can be used for fabricating the more advanced multi-asymmetric particles.
