An is disclosed. The apparatus comprises a two-dimensional perovskite having a polaronic emission Stokes' shifted by at least 50 nm to minimise loss due to re-absorption.

Apparatus for radiation detection

Various embodiments may provide a device for providing a first optical light of a first wavelength and a second optical light of a second wavelength. The device may include a halide perovskite structure including a first pattern and a second pattern different from the first pattern, so that the first pattern is configured to provide the first optical light of the first wavelength and the second pattern is configured to provide the second optical light of a second wavelength different from the first wavelength, upon a light incident on the first pattern and the second pattern. The halide perovskite structure may include a halide perovskite material.

Device including halide perovskite structure, methods of forming and operating the same

In various embodiments, a light-emitting device may be provided including an active structure including a halide perovskite layer. The light-emitting device may further include a first injection electrode and a second injection electrode electrically coupled to the active structure. The light-emitting device may additionally include a control electrode, and an insulator layer between the control electrode and the active structure. The first injection electrode may be configured to inject electrons into the active structure and the second injection electrode may be configured to inject holes into the active structure upon application of a potential difference between the first injection electrode and the second injection electrode. The control electrode may be configured to generate an electric field upon application of a voltage, thereby causing accumulation of the electrons and the holes in a region of the halide perovskite layer so that the electrons and the holes recombine, thereby emitting light.
