US 4,230,510 A · Distributed phosphor scintillator structures

Abstract

Distributed phosphor scintillator structures providing superior optical coupling to photoelectrically responsive devices together with methods for fabricating said scintillator structures are disclosed. In accordance with one embodiment of the invention relating to scintillator structures, the phosphor is distributed in a layered fashion with certain layers being optically transparent so that the visible wavelength output of the scintillator is better directed to detecting devices. In accordance with another embodiment of the invention relating to scintillator structures, the phosphor is distributed throughout a transparent matrix in a continuous fashion whereby emitted light is more readily transmitted to a photodetector. Methods for fabricating said distributed phosphor scintillator structures are also disclosed.

Dependent claims

A method of manufacturing multilayered scintillator bodies to increase detectable output at optical wavelengths when excited by high energy photons at supra-optical frequencies, said method comprising the steps of:

(A) applying a uniform layer of phosphor material to at least one side of each of at least two rigid substrates, said substrates being inert, transparent to radiation at supra-optical frequencies, and having substantially flat sides;
and then
(B) forming a further layered structure by disposing an optically transparent material between layers of the phosphored substrates from step A, said laminate material being transparent to radiation at supra-optical frequencies, whereby optical wavelength output produced within the scintillator body is channeled to the exterior of the body for detection.
