Potential for light emission: Investigations into quantum dots as phosphors and in light-emitting electrochemical cells

Semiconductor nanocrystals, known as quantum dots (QDs), have unique optical
properties that makes them useful for application in various light-emitting devices, such
as LEDs, displays and lasers. For actual application of QDs, energy efficiency of their light
emission and material stability are crucial. To achieve high energy efficiency, it must be
understood which types of atomic defects on the nanocrystals lead to energy losses and
how to prevent them. To achieve stable QDs, it is important to understand which kinds of
chemical reactions the QDs can undergo, if these reactions lead to the formation of new
defects and how to prevent this...
