The article describes the pathway to the invention of blue LED based on GaN. Fluorescent conversion of the blue emission into the white light makes blue LEDs especially versatile. The new white light source is effcient, durable and environmentally friendlyIsamu Akasaki in Hiroshi Amano z Univerze v Nagoji ter Shuji Nakamura, ki je deloval v podjetju Nichia Chemicals na Japonskem, sedaj pa je profesor v ZDA, so letošnji Nobelovi nagrajenci zafiziko. Članek opiše pot do izdelave modre LED na osnovi GaN. Posebej uporabna pa je modra LED v kombinaciji s fluorescenčno pretvorbo v belo svetlobo. Tako smo dobili izvor bele svetlobe, ki je učinkovit, ima dolgo življenjsko dobo in je okolju prijazenTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo matematikov, fizikov in astronomov
