Abstract:
A porous scintillator crystal capable of suppressing scattering of light that represents a high spatial resolution is provided. The porous scintillator crystal comprises a porous structure including voids, wherein the porous structure is a phase-separated structure having voids formed therein and comprises materials constituting a eutectic composition of the phase-separated structure and at least one void in the porous structure extend in a direction perpendicular to a principal plane of the porous scintillator crystal.
Abstract:
In a scintillator used for radiation detection, such as an X-ray CT scanner, a scintillation crystal body having a unidirectional phase separation structure is provided which has a light guide function for crosstalk prevention without using partitions. The phase separation structure includes a first crystal phase and a second crystal phase having a refractive index larger than that of the first crystal phase and which have a first principal surface and a second principal surface, these principal surfaces being not located on the same plane, the first principal surface and the second principal surface have portions to which the second crystal phase is exposed, and a portion of the second crystal phase exposed to the first principal surface and a portion of the second crystal phase exposed to the second principal surface are connected to each other.
Abstract:
A stable FePt plating solution is provided. Further a process for electroplating is provided for producing an FePt magnetic material having especially strong coercive force and excellent properties by use of the plating solution. The plating solution contains ionic Fe, ionic Pt, and a complex agent, at a molar ratio (Fe/Pt) of the ionic Fe to the ionic Pt ranging from 0.75 to 3.
Abstract:
Provided is a scintillator having a function of waveguiding scintillation light to a photodetector and having a structure for increasing an amount of absorption of radiation. The scintillator has a first surface (10) and a second surface (11) which are not located on a same surface, and includes: a first phase (12); and a second phase (13) having a refractive index higher than that of the first phase and having a linear attenuation coefficient different from that of the first phase, in which one of the first phase and the second phase includes multiple columnar portions arranged in a direction from the first surface to the second surface, and the multiple columnar portions are stacked in a state in which end faces of the columnar portions are partly offset with respect to each other in a direction parallel to the first surface or the second surface.
Abstract:
Provided is a scintillator used for radiation detection in an X-ray CT scanner or the like, the scintillator having a unidirectional phase separation structure having an optical waveguide function, which eliminates the need of formation of banks for preventing crosstalk. The scintillator has a waveguide function instead of the banks or the like. The scintillator includes: a first crystal phase including multiple columnar crystals having unidirectionality; and a second crystal phase for covering a side of the first crystal phase. The first crystal phase includes a perovskite type oxide material including at least one element selected from the group consisting of Lu and Gd, and a rare earth element as an emission center. The first crystal phase emits light by radiation excitation.
