I tried sending this via email, but it bounced.

"Durham, NC -- Cree Research, Inc. has built the missing link in
    full-color light-emitting diode (LED) displays -- a pure blue emission
    diode.  Three families of silicon carbide blue LEDs use a low power
    peak wavelength to produce the purer blue.  LEDs are semiconductors
    that produce visible when connected to an electrical power source.
    List prices for Cree's die are $1.47 in 100,000-unit quantities --
    that's about a tenth the cost of the competetion, Cree says.  By
    combining the new blue with red and green LED chips, designers can
    produce any color light in the visible spectrum, including white.  For
    more information, call Cree at (919)-361-5709."

"For years, the industry has awaited the advent of a blue LED.  These
unique silicon emitters are now available at prices between $12 and
$15 each. Operating at 470 nanometer wavelengths, 100,000-hour LEDs
come in both single- and multi-chip configurations.  LEDTRONICS, 4009
Pacific Coast Highway, Torrance, CA 90505. (213) 549-9995"


These are both from articles posted to sci.electronics a few weeks
ago.
