Molecular rings mystery solved after 20 years

The two benzene rings in a benzene dimer can have one of two configurations: flat on top of one another (left) or one flat and the other upright on top (right).Although the double benzene molecule tried to reveal its structure in experiments in 1993, ... [Published PhysOrg.com - Apr 16 2013]

The project "Cadmium-free all-inorganic quantum dots as down-conversion LED phosphors (CadFrinDot)” will deal with the development of inorganic indium phosphide-based quantum dots for converting to longer-wave light in LEDs. Colloidal quantum dots are regarded as ideal candidates to replace today's (red) phosphors in LEDs as they can considerably increase LEDs’ efficiency. Existing quantum dot phosphors have disadvantages, however: they are cadmium-based, do not lead to stable photoluminescence in the long term, and they are difficult to build into the required matrix material. Arjan Houtepen from the Delft University of Technology oversees this project which aims for alternatives to cadmium-based LED materials."

Van der Avoird explained: "The old model was not wrong, but it was very complicated. As a result, the computer calculations made using the model were too inaccurate to be able to calculate the peak patterns. I therefore needed to pare the model down to the basics, after which the spectral patterns just rolled out of the calculations. The key to success was the insight that the rings rotate in synchronisation. They work together to switch rapidly between one energy minimum and another. This results, via the quantum tunnelling process, in the recorded peak patterns."
