Historically, black body radiation in the tungsten filament lamp
was our primary industrial means for producing 'artificial' light,
as it replaced gas lamps. Solid state luminescent devices for
applications ranging from lamps to displays have proliferated since
then, particularly owing to the develop ment of semiconductors and
phosphors. Our lighting products are now mostly phosphor based and
this 'cold light' is replacing an increasing fraction of tungsten
filament lamps. Even light emitting diodes now chal lenge such
lamps for automotive brake lights. In the area of information
displays, cathode ray tube phosphors have proved themselves to be
outstandingly efficient light emitters with excellent colour
capability. The current push for flat panel displays is quite
intense, and much confusion exists as to where development and
commercialization will occur most rapidly, but with the need for
colour, it is now apparent that solid state luminescence will play
a primary role, as gas phase plasma displays do not conveniently
permit colour at the high resolution needed today. The long term
challenge to develop electroluminescent displays continues, and
high performance fluorescent lamps currently illuminate liquid
crystal monochrome and colour displays. The development of tri
component rare earth phosphors is of particular importance."
