First discovered in 1980, colloidal semiconductor nanocrystals or quantum dots (QDs) are typically between 2 – 10 nanometres (nm) in diameter and are now being commercialised with possible applications in a variety of thin film devices including solar cells, photodetectors and LEDs. QDs have profound implications for the flat panel display (FPD) industry, but is it really a case of all change from here on in?
