Does anyone know if _blue_ L.E.D.s exist? If so, from whom are they available?
Thanx in advance,
Tim North

Yes, they exist. They are *EXTREMELY* expensive, at least when I checked last. An old catalog (1988) that I have has a price of $50 (!) for the blue and about $0.50 for red/green/yellow. Quantities of one. -- Real life: Thomas Tornblom Email: thomas@uplog.se Snail mail: TeleLOGIC Uppsala AB Phone: +46 18 189406 Box 1218 Fax: +46 18 132039 S - 751 42 Uppsala, Sweden

Reading in Science News I understand that there are some new processes that promise to lower the prices of the blue LEDs. Important for oh say making TVs out of em I guess. But I'd really like to know what they're using that has such a large band gap, or are they multipliing the frequency?? Please respond via e-mail. kr
