    The film on the inside of the CRT tube is a Phosphor coating. See here: Parts of a Cathode Ray Tube
    Then look here on wiki: Phosphor and there is a sections that says what is. Not sure if you can scrap it or not (assume you can), but you would have to vacuum A LOT of tubes in order to get enough to make it worth while. It is a very very thin film!
    Hope it helps!
