This is a very useful site! Thank you for putting it together.
I have a question regarding the refractive index of the scintillator BGO. It is usually quoted at around 2.15 at the emission maximum (480nm)
http://www.detectors.saint-gobain.com/BGO.aspx
Yet, it is listed here at 2.57 in 588 nm which, given the Abbe number is, increases to 2.67 at 480 nm. Also, Here is a peer-reviewed publication which lists the index at 2.15
