Breaking Kasha's rule: Scientists find unique luminescence in nanocrystals

Named for chemist Michael Kasha, who proposed it in 1950, Kasha's rule holds that when light is shined on a molecule, the molecule will only emit light (fluorescence or phosphorescence) from its lowest energy excited state. Highly luminescent molecular systems crafted from quantum dots that break Kasha's rule have not been reported - until now.

Nanowires offer opportunities for improved LEDs

Researchers from the FOM Institute AMOLF, together with colleagues from Philips Research, Eindhoven University of Technology and Delft University of Technology, have made special nanostructures that could be used as light-emitting diodes (LEDs). These nanostructures can be used to control the direction of the emission.

Shedding light on Kondo correlations

Scientists from ETH Zurich, LMU Munich, Princeton and Yale Universities have used resonant laser absorption to examine how a quantum dot with Kondo correlations responds to a quantum quench, i.e. to an abrupt change in the interactions that give rise to Kondo correlations in the first place.

Guitar hero? Special thin-film on guitar converts string tension into digital control signals

Guitar virtuosos have to master all kinds of playing techniques. But how can the intricate process of playing the instrument be captured digitally? A special thin film on the tailpiece has the answer. Functioning as a sensor, it converts the tension on the string into digital control signals.
