Title: Data on CRT phosphors
Post by: Opcom on March 11, 2009, 03:26:18 AM
Here is more than you will ever want to know about CRT phosphors unless you are a chemist. This includes RMA/EIA numbers P1 to P56 and also crosses some EU or international types using the two-letter designation.

It's not a CRT manual, but a detailed report consisting of a 78 row table of phosphor types listing flourescence and phosphorescence colors, emission bandwidths and peak wavelengths, chemical compositions, subtle differences, and intended purposes.

You also get to find out what happened to -P8 and -P9 and see how the -P4 evolved with time.

Why turn down that oddball $5 NOS CRT at the hamfest because it's a P17 or P43 and no one knows what that is?

If anyone has a -P10 lying around I would be interested in pictures. Never seen one of those.
