Abstract: A light source using a light-converting material, in particular for the conversion of collimated or focused light, which does not operate solely on the principle of geometric concentration as known from the prior art, but which reflects light away from the interface between the surface of the conversion body (1) and the surroundings due to the high refractive index of the conversion body (1), possibly by means of an applied reflective layer. The light source uses the high refractive index and high transmittance of the phosphor material as the properties necessary to direct the light in the desired direction directly by the conversion body (1) itself. The light source emits collimated or focused intense secondary light, or a homogenised mix of primary and secondary light, or it may transmit supplementary light.

Abstract: An optical element (1) comprises: a body (2) of radiation converting monocrystalline material, e.g. of a luminescent or scintillator material, and an extraction structure (4, 6) applied to at least one output or input surface of the body (2); wherein the extraction structure (4, 6) is constructed and configured such that radiation at an output (19) of the body (2) is directionally modified, especially in terms of energy or intensity or of directional distribution or of both, as compared with radiation at the output of the body (2) in the absence of said extraction structure (4, 6), by interaction of radiation entering and/or propagating within and/or exiting the body (2) with the said extraction structure (4, 6), e.g. such as to reduce or ameliorate the deleterious effects of TIR within the body (2).

Abstract: A single crystal yttrium aluminum perovskite scintillator has a minimum thickness of at least 5 mm and a transmittance of at least 50% at a wavelength of 370 nm. A method for fabricating the yttrium aluminum perovskite scintillator includes acquiring a yttrium aluminum perovskite single crystal boule, annealing the yttrium aluminum perovskite single crystal boule in an oxygen containing environment to obtain a partially annealed crystal, and annealing the partially annealed crystal in an inert environment or a reducing environment to obtain the yttrium aluminum perovskite single crystal scintillator.
