I am about a year younger than you and have two copies (quite a few years apart) of the CRC Handbook, one of which I have read very heavily during my teen years and to a lesser extent but still significantly afterwards.
How does the CRC Handbook support silicon or any major active ingredient of any of the usual "semiconductor LEDs" being organic?
Heck, the usual "semiconductor LEDs" don't have silicon anyway unless they are flashing / color-changing ones or otherwise including a semiconductor die other than the one(s) used to produce light.
For that matter, what do you expect to accomplish by saying "retarded reply" other than to have Copacetic added to the list of multiple nyms appearing to be used by the one often referred to as "nymbecile" and "dimbulb"?
