Abstract
A detailed background into the reasons for the
feverish interest and growing impact on commercial market share of
organic light-emitting diode (OLED) technology for lighting and display
applications is given. Following this, the increasing discussion over
whether electroluminescent devices based on quantum dots will ever
challenge that of organics in displays is considered. The unique physics
and chemistry of quantum dots results in narrow emission bands and
increased stability over organic dyes meaning the potential for this
is significant. The current best efficiencies of quantum dot devices
and associated device structures from the literature are presented
followed by a comparison of devices fabricated with organic materials,
in particular those of polymers, metal complexes (fluorescent and
phosphorescent) and small molecules.
