development of exciplex emitters for organic light-emitting diodes (OLEDs) has witnessed …

Recently, organic thermally activated delayed fluorescence (TADF) emitters have attracted a
great deal of attention because they can theoretically realize 100% internal quantum …

Low-cost and large-scale fabrication technologies are highly desirable for fabricating
organic light-emitting diodes (OLEDs) for applications in full-color displays and solid-state …

A simple technique employing reverse bias measurements of photoluminescent efficiency is
described to determine the excitonic singlet-triplet formation statistics of electroluminescent …

The basic photophysics, transport properties, state of the art, and challenges in OLED
science and technology, and the major developments in structurally integrated OLED-based …

Publisher Summary This chapter discusses the new semiconductor device physics that can
be realized using thin films of semiconducting polymers as the active layers, in devices …

Organic light-emitting devices (OLEDs) are a promising technology for flat-panel displays
and solid-state lighting. While OLED efficiencies have increased dramatically in recent …

The authors report a study of the photophysical properties of poly (p-phenylene vinylene),
PPV, prepared in a way that gives an especially high degree of intrachain order. Optical …

We show that one-electron band theory fails to describe optical absorption in PPV and the
absorption spectrum can be described only within a Coulomb-correlated model. The lowest …
