New research ha revealed that nanocrystals made of cesium lead halide perovskites is the first discovered material which the ground exciton state is 'bright', making it an attractive candidate for more efficient solid-state lasers and light emitting diodes (LEDs).
Scientists have been working to develop a new process, which could lead to a new generation of high-definition (HD), paving the way for brighter, lighter and more energy efficient TVs and smart devices.
New research has demonstrated how the nano-architecture of a silkworm?s fiber causes 'Anderson localization of light', a discovery that could lead to various innovations and a better understanding of light transport and heat transfer.
Through a collaborative approach of advanced spectroscopy and theoretical modelling, researchers were able to establish that the migration of excitation energy greatly affects the upconversion dynamics.
Fullerenes were first discovered by Harry Kroto in the 1970s, a feat for which he and his colleagues received a Nobel Prize in Chemistry. Recently, they have been found in winds emitted by red giants and in interstellar medium.
A research team has realized strong coupling between distant phonon modes, by introducing a third resonator as a phonon cavity mode. Varying the resonant frequency of the phonon cavity mode, the coupling strength between distant phonon modes can be continuous tuned.
