Abstract: The invention relates to a method of producing a crystal from a material with the general composition of CexGdyY1?x?yAlO3 known to the professional public for scintillation crystal detectors, which has not yet been industrially produced by the Czochralski method. The invented method makes it possible to produce crystals with a diameter larger than units of mm. In particular, the invention adds to the initial Czochralski method the steps of annealing the input raw materials as well as the controlled flow of a reducing hydrogen-argon atmosphere through a crystal growth furnace.

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.

Abstract: According to the invention, the diode with a single crystal phosphor placed over the chip selected from the InGaN, GaN or AlGaN group comprises the fact that the single crystal phosphor (21) is created from the monocrystalline ingot (51), created by LuYAG or YAP hosts, doped with the atoms selected from the Ce3+, Ti3+, Eu2+, C, Gd3+ or Ga3+ group, grown from the melt with the method selected from the Czochralski, HEM, Badgasarov, Kyropoulos or EFG group, when the Lu3+, Y3+ and Al3+ atoms can be replaced in the host up to the amount of 99.9% with the B3+, Gd3+ or Ga3+ atoms.

Abstract: According to the invention, the diode with a single crystal phosphor placed over the chip comprises the fact that the single crystal phosphor, created by LnYAG and/or YAP and/or GGAG hosts, doped with the atoms selected from the Ce3+, Ti, Cr3+, Sm2+, B3+, Gd3+ or Ga3+ group, when the Lu3+, Y3+ and Al3+ atoms can be replaced in the host up to the amount of 99.9% with the B3+, Gd3+ or Ga3+ atoms. The composition and manner of production of the phosphor, treatment and shape of its surface and construction of the whole diode ensure the extraction of the converted light in the direction from the chip itself of the diode towards the object that is being illuminated and limit the total reflection effect on the interface of the single crystal phosphor and encapsulant or single crystal phosphor and surrounding environment.
