Odd CRT effects.

[twistedpneumatic]

I found some odd behavior from my 4 mono-CRTs that I have out in the open.

13" TV - White phosphor, no glow, small effect from UV
12" Apple - Green phosphor, very little glow, bright effect from UV
12" PET - Green phosphor, glows very brightly, small effect from UV
12" IBM - Amber phosphor, no glow, no effect from UV

Kind of interesting. Little video demonstrating all the effects. Very interesting that amber has no reaction to UV light.

The "phosphors" used in them are chemically very different. Somewhere I have a booklet that explains all the different phosphors used and their properties.
