A method of manufacturing a scintillator material includes providing a substrate made of a quartz glass and having a recess formed therein; filling the recess with a raw material powder obtained by mixing an iodide raw material and SiOfine particles; after filling the recess, disposing a lid on the substrate to cover the recess; and after disposing the lid, heating the substrate, thereby forming a nanocomposite layer in which an iodide phosphor is introduced into a cristobalite structure.

Manufacturing method of scintillator material and scintillator material

Provided is a display system for a vehicle. The display system includes a display device installed to be visually recognizable from the outside of a vehicle, and a control device configured to cause the display device to display state information of the vehicle. The control device receives a signal from a sensor that senses a distance from the vehicle to an object around the vehicle, and the control device changes display of the display device based on the distance.

Display system for vehicle

A nanocomposite includes: a matrix phase; and a functional area disposed in the matrix phase. The functional area contains monocrystal fine particles.

Nanocomposites and method of manufacturing nanocomposites

A method for preparing a phosphor that comprises a crystalline oxide having MO(Mis a tetravalent metallic element) as a main framework thereof and essentially including a halogen element X (X is at least one element selected from a group consisting of F, Cl, Br, and I) and divalent metal ions Mand Eu, includes using a compound represented by a compositional formula NHX as a starting material when synthesizing the phosphor. At least a compound represented by a compositional formula NHCl may be used as the starting material.
