A motor vehicle headlight capable of emit, with a single light source, two beams of differentThe headlight comprises a light source and a reflector (30) which can be moved relative to one another to give two different beams. The light source is fixed to one component (50) of the ...
The interaction of light with a single two-level emitter is the most fundamental process in quantum optics, and is key to many quantum applications. As a distinctive feature, two photons are never detected simultaneously in the light scattered by the emitter. This is commonly interpreted by sayin...
Light-emitting diodes (LEDs) are an indispensable part of our daily life. After being studied for a few decades, this field still has some room for improvement. In this regard, perovskite materials may take the leading role. In recent years, LEDs have become a most explored topic, owing to...
Perovskite light-emitting diodes (LEDs) are attracting great attention due to their efficient and narrow emission. Quasi-two-dimensional perovskites with Ruddlesden–Popper-type layered structures can enlarge exciton binding energy and confine charge carriers and are considered good candidate materials for ...
a small enough volume to cause a detectable excitation. Such high intensity can damage the system under investigation. Because the temporal andspatial correlationsmay be much stronger between members of anentangled photonpair, much weaker light sources could be used, which would be much less ...
15.The package of claim 1, further comprising at least one septum formed in a single body along with the main body to separate the at least two heat sinks. 16.A high power light emitting diode package comprising:an insulation main body;at least two lead terminals fixed to the main body;...
An apparatus comprising a base, a heat sink, a plurality of thermal elements, and a plurality of LED elements. The base may be configured to attach to a screw in light socket. The heat sink may be connected to the base. The plurality of thermal mounts may project from the heat sink. ...
The small satellite, optimised for early photometry of kilonovae, will be particularly well suited for the follow-up observations of a wide range of transient sources, such as gamma-ray bursts (GRBs, Piran2004; Zhang and Mészáros2004; Mészáros2006; Kumar and Zhang2015), supernovae (SNe,...
Carbon dots have been gaining attention in the field of nanobiotechnology due to their superior photostability, high water solubility, ease of synthesis and surface functionalization, chemical inertness, low toxicity, and excellent biocompatibility. They
The advent of free-electron laser (FEL) sources delivering two synchronized pulses of different wavelengths (or colours) has made available a whole range of novel pump–probe experiments. This communication describes a major step forward using a new configuration of the FERMI FEL-seeded source to ...
