A scintillator unit with less light leakage from a scintillator to an adhesive layer and a radiation detector that can improve sensitivity to radiation and the resolution of an image to be formed. Specifically disclosed is a scintillator unit including an adhesive layer between a scintillator and a supporting member and a low-refractive-index layer with a lower refractive index than the adhesive layer between the scintillator and the adhesive layer.

Scintillator unit and radiation detector

A scintillator unit that can reduce crosstalk when the scintillator unit includes a plurality of scintillators and a radiation detector are provided. More specifically, a scintillator unit includes a reflective layer between a plurality of scintillators and the plurality of scintillators, wherein an adhesive layer and a low-refractive-index layer with a lower refractive index than the adhesive layer are located in this order on the scintillators between the scintillators and the reflective layer.

A photoelectric conversion device, including: a photoelectric conversion substrate having a plurality of photoelectric conversion portions and a microlens array arranged on the plurality of photoelectric conversion portions; a light-transmitting plate covering the microlens array; and a film arranged between the microlens array and the light-transmitting plate, wherein the film has a refractive index within a range from 1.05 to 1.15, an average transmittance of light in a wavelength region within a range from 400 nm to 700 nm of 98.5% or higher, and a film thickness within a range from 500 nm to 5000 nm.

Photoelectric conversion device, and equipment

A film forming method includes forming a film on a substrate, in which the film includes first regions, second regions, and third regions, the first regions, the second regions, and the third regions being defined by a refractive index and a region size and being present in a mixed manner in a cross section parallel to a thickness direction, the first regions and the second regions have a refractive index at least 0.4 higher than the third regions, the second regions are formed of high-refractive-index particles having an average particle size of 10 nm or more and 100 nm or less, the first regions are formed of the high-refractive-index particles that have been aggregated, the first regions having an equivalent circular diameter of 250 nm or more, and the third regions have an equivalent circular diameter of more than 100 nm.
