Re: I have red, green and violet (sold as blue) laser pointers.

For the glow-in-the-dark question, the violet laser will have higher-energy photons and so will be kicking whatever it is needs to be kicked into an excited energy level. The other lasers will then either give whatever it is enough of a kick that it falls back rapidly or, perhaps, kick it into some yet other excited energy level where it is much more nearly stable, so appears dark.
