The Chemical Society of Japan will co-organize "JAPAN-SWEDEN Science, Technology & Innovation Symposium 2014 in STOCKHOLM".
Collection of abstracts is here
The symposium is focused on Blue LED, scientific breakthrough with real world impact and organized by Royal Swedish Academy of Engineering Sciences; IVA, Japan Society for the Promotion of Science, Sweden-Japan Foundation, Embassy of JAPAN, STOCKHOLM, Meijo University, and Chemical Society of Japan.
The aim of this symposium is to introduce to the science and technology community in Sweden, a seminal global contribution originating from Japan in science, technology and innovation. For this event, we invite a Japanese scientist who has brought about substantial impact on our life and society, enabling our current prosperity with sustainability, gaining perspective on the key to success in research and development, know-how in launching a new business, and how to forecast future market developments.
In the 1960’s red and yellow-green light-emitting diodes (LEDs) and infrared semiconductor lasers (LDs) were already realized. But there was no prospect of practical blue-lightemitting devices. In 1973, Professor Isamu Akasaki decided to develop high-performance blue-light-emitting devices based on GaN p-n junctions. And in 1986 he and his group at Nagoya University created the first electronic-grade high-quality GaN single crystalline material. In 1989, they developed the first GaN p-n junction blue LED.
The development of blue and green LEDs has completed the set of LEDs for the three primary emission colors. Coupled with available high-brightness red LEDs, they imply the development of solid-state full-color displays, traffic lights, signage, and specialized lighting applications.
White LEDs are now being used in TVs, cell phones and displays and beginning to be applied to lighting equipments in houses, offices, factories and outdoors. The UV-LEDs will be used in sterilization, microscopic level diagnoses, and medical treatment.
All of these GaN-based devices are robust, and they enable significant energy savings. Their use will be a major weapon in the fight against global warming.
