US Patent 7150910 - Nanocrystal Grating
http://www.freepatentsonline.com/7150910.pdf
One of the promising applications of nanocrystals derives from their size dependent band gaps which can produce optical amplification effects useful for lasers. This patent from M.I.T. teaches nanocrystals arranged with a particular periodicity to optimize such amplification effects. Claim 1 reads:
1. A structure comprising: a grating having a periodicity from 200 nm to 500 nm; and a semiconductor nanocrystal layer disposed on the grating, the layer including a plurality of semiconductor nanocrystals.
