Photonic-Crystal Scintillators: Molding the Flow of Light to Enhance X-Ray and γ -Ray Detection

Ultrahigh Spatial Resolution, Fast Decay, and Stable X‐Ray Scintillation Screen through Assembling CsPbBr3 Nanocrystals Arrays in Anodized Aluminum Oxide

“…From the light-management perspective, the 3D nanowires array is an inhomogeneous optical system whose response to light can show a complicated dependence on the geometrical parameters. [33][34][35] As a result, we have simulated the light distribution at the bottom of the hexagon array scintillation screen emitted by the point light source with a depth of 10 µm in the center, using FDTD algorithm [36] and Geant4 code [37][38][39] to simulate and compare at the same time.…”

Halide perovskites scintillators: unique promise and current limitations

“…This is achievable using photonic structures, which have recently emerged as a potential concept to improve the performance of existing high refractive index scintillators. [123][124][125][126] Increasing the cone of emission will improve light yields of scintillators, with simulations suggesting 90-110% enhancements 124 , and increase the timing resolution, by increasing the likelihood that light is emitted at the first instance it meets the scintillator/detector interface, increasing the light yield at early times. 123 Spatial resolution would also improve through decreased lateral distances between the point of emission and detection by the photodetector.…”

Luminescent Photonic Crystals with Extreme‐UV Bandgaps Made of CuInSe2 Quantum Dots

“…[ 32 ] The embedment of the X‐ray/γ‐ray scintillator materials (rare‐earth metal ions) in a PhC leads to their directional visible emission and fivefold enhancement in the number of the detectable photons. [ 33 ] In nature, the elytras of some insects contain the fluorophores embedded in a porous photonic structure, and this composite structure controls both the insect color and its fluorescence. [ 34 ] Herein, we study the PhCs made of the fluorescent ultrasmall colloidal CuInSe 2 QDs, in which the CuInSe 2 QDs act as both the building blocks and fluorophores.…”
