Quantum Dots as a Light Indicator for Emitting Diodes and Biological Coding

Abstract

This article discusses on quantum dots (QDs) as a light indicator for emitting diodes and biol. coding. Due to their unique elec. and optical properties, quantum dots are excellent candidates to be used as indicators in very diverse applications. Not only size, shape and compn. dependent color but also high quantum yield and stability against photobleaching are the key of their potential success in many areas from electronics to biol. and medical diagnostics. In the field of light emitting diodes, they can be combined either with other different size QDs or org. electroluminescent materials in order to fabricate tunable light emitting devices. In the same way, embedding and coating different size QDs onto microbeads can lead to create multiple optical codes for biomedical applications. [on SciFinder(R)]
