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.

Does it have to be that material? Have you looked here -> http://www.stanfordmaterials.com/ph.html ?

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

Never mind, after 7 hours of searching I found a supplier!

Meller Optics if anyone cares.
