Doping of organic semiconductors [PDF]

physica status solidi (a), 2012
AbstractThe understanding and applications of organic semiconductors have shown remarkable progress in recent years. This material class has been developed from being a lab curiosity to the basis of first successful products as small organic LED (OLED) displays; other areas of application such as OLED lighting and organic photovoltaics are on the verge

Single-photon upconversion via hot-band absorption and assessment of the laser cooling effect of tricarbocyanine dyes

Chemical Physics Impact, 2021
A series of new tricarbocyanine near-infrared (NIR) dyes is demonstrated which are able for a single-photon vibronic-assisted anti-Stokes luminescence with a large, up to 147 nm (225 meV), anti-Stokes shift of the excitation energy.
