I remember those old color console TV sets. There were color knobs on them that you had to turn if there was too much red, green, or blue in the picture. The cathode tubes inside could be replaced.
It sounds reasonable. According to Wikipedia the red phosphor (Y2O2S:Eu+Fe2O3) was the bottleneck for the development of colour TV so it wouldn't surprise me that is was also the 'weakest link'.
@Morpun I doubt that. These videos don't teach you about all the logic of chemistry. Your college must have taught you WHY these reactions occur, and give numbers to them.

What's also interesting is that Europium in the nitrate form is used for commercial glow powder.

It absorbs neutrons...probably more than any other element. It's used in the control rods of some nuclear reactors.

I remember old televisions going funny when displaying red. Does this have anything to do with europium?
