Highly Efficient Light Emitters - The Root to Green Laser
The emission of green laser light is of great importance for several applications and procedures particularly in biology, medicine or multimedia. A powerful green laser could revolutionise the market for portable beamers. So far, semiconductor based light emitters, such as laser pointers, convert infra-red into green light (Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology). A significant drawback of this technique is the loss of power and efficiency. In addition, those devices are limited when it comes to reduction in size for use in integrated devices.
The new technology involves a Zn-Cd- semiconductor material that features a band gap in the 2,2 eV - 2,5 eV range which allows the emission of green light. Contrary to current state of the art techniques the innovative technique produces a semiconductor material that is capable to emit green light directly. Ongoing development demonstrated successfully the optical induced emission of green light.

International research team makes important step on the path to solving certification problems
Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale
Researchers from the Institute of Organic Chemistry and Biochemistry of the CAS (IOCB Prague), Institute of Physics of the CAS (IP CAS) and Palacký University...
For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
