Abstract: A scintillator panel includes a substrate having a front side and a rear side. A first scintillator layer is embedded into the front side of the substrate to a first depth. A second scintillator layer is embedded into the rear side of the substrate to a second depth.

Abstract: An electromagnetic wave conversion structure consists of a substrate, a plurality of electromagnetic wave conversion units forming a two-dimensional array, a reflective film and a plurality of reflective layers. The substrate has a first surface and a second surface disposed opposite to the first surface. The second surface consists of a plurality of trenches formed in the body of the substrate. Each electromagnetic wave conversion units is disposed in each trench, is used to absorb first electromagnetic waves with a first wavelength and is used to emit second electromagnetic waves with a second wavelength. The first wavelength is shorter than the second wavelength. The reflective film covers the first surface of the substrate and is used to reflect the second electromagnetic wave. Each of the reflective layers is disposed on the sidewall of each trench of the corresponding electromagnetic wave conversion unit.
