ABSTRACT:
Scintillator structures are disclosed in which the phosphor is embedded or suspended in an optically transparent matrix which is selected or adjusted to have an index of refraction which is approximately equal to that of the phosphor embedded therein at the wavelength of the light emitted by the phosphor. In accordance with one embodiment of the invention, BaFCl:Eu is embedded in a matrix formed by the polymerization of 2-vinyl napthalene and vinyl toluene. The scintillator structures of the present invention provide superior optical coupling to photoelectrically responsive devices. Also disclosed are methods for manufacturing index-matched phosphor scintillator structures.
