Anyone know where I can get some phosphors?

    This is a bit random, but does anyone have any idea where I can get some Chromium doped Ruby spheres (Cr:Al2O3) or maybe just powder form? I need to build some fiber optic temperature probes for part of my masters thesis but I can't find this stuff anywhere except in liquid form. Apparently, its a cheap and commercially available material as its suppose to be used for lasers but I can't find it anywhere. :cry:

    It doesn't absolutely have to be that material but it does need to be something with similar atomic structure and/or fluorescent properties.
