The paper reviews the reasons behind an interest in studying the properties of nanostructured layers in the context of using ion implantation as a method of creating layers with high concentration of metal or semiconductor nanoclusters. Layers of metallic nanoclusters in transparent materials exhibit strong non-linear optical properties thus making them suitable candidates for photonic materials. On the other hand, semiconducting nanoclusters are studied as candidates for materials with strong luminescence coupled with a possibility of easy tuning the emitted wavelength.
Peculiarities and advantages of ion implantation as a versatile and flexible method of forming such nanostructured layers are discussed. The usefulness of this method is presented on such examples as:
- implanted nanoclasters of Au , Ag, and Cu in MgO and fused silica,
- diamond nanoclusters in fused silica,
- nanoclusters of compound semiconductors in silica,
- nanocrystals with "core-shell" structure formed by co-implantation.
Current problems and future prospects of using ion implantation in the domain of nanotechnology are presented.
