Interesting paper on CRT & VFD phosphor types...

[Nick]

Found this in my archives, by Patrick Jankowiak - lot of good information relevant to those building CRT clocks & doing stuff with VFDs etc.

I have a suspicion that I originally got it from http://www.bunkerofdoom.com/ - a great site...

Hi Nick

I found the same document from 

https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=11&ved=0CG8QFjAK&url=http%3A%2F%2Famfone.net%2FAmforum%2Findex.php%3Faction%3Ddlattach%3Btopic%3D18928.0%3Battach%3D10886&ei=twg1U_eBF8GMkAXtuoHQCA&usg=AFQjCNEOcyrIZyBCiLx6-vzULwnw7QDDnQ&sig2=-FyzDrrgtyDhE31VoD8-FQ&bvm=bv.63808443,d.dGI&cad=rjt. 

Despite the long URL AVG said it was a clean site so I took the risk and downloaded it. No trouble so far and that was about 3 months ago.

This is also interesting http://www.phosphor-technology.com/products/crt.htm

Cheers

Russian CRT phosphor designation

I = Green medium short persistence  Similar to UK/US P1

V = Yellow green fluoresce with long yellow persistence

M = Short persistence blue florescence  Similar to UK/US P11

I just checked - "Bunker of Doom" is Patrick Jankowiak's own site - the correct URL for the document is http://www.bunkerofdoom.com/tubes/crt/crt_phosphor_research.pdf

The actual URL embedded in that Google search value you had is http://amfone.net/Amforum/index.php?topic=18928.0 but the correct home page for the document is definitely at the author's own site above.

EDIT: Just noticed that the poster of the above article on AMforum was Peter himself!
