Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a dual-state functional material radiation sensing device and an assembly method thereof. Background technique [0002] A radiation detector is a device used to detect high-energy particles. It is mainly composed of a scintillator, a photoelectric conversion device, readout electronics and an image reconstruction module, among which the scintillator is an indispensable and important part. The detection process of the radiation detector is that radiation particles are injected into the scintillator of the detector, and then the incident particles deposit energy in the detector through ionization, excitation and other effects and emit visible fluorescence, and then the detector converts the visible fluorescence to It is a certain form of analog electrical signal, and then the analog electrical signal is further converted into an easy-to-operate digital electrical sig...

Problems solved by technology

[0005] (3) The scintillators used in traditional radiation sensing devices are generally solid crystals, which makes the type of high-energy particles absorbed by the radiation sensing device too single, and because solid crystals are all formed of rare earth elements, and rare earth elements are especially The reserves of heavy rare earths are very scarce, which makes it difficult to reduce the production cost of radiation sensing devices

However, when the absorption intensity is large, the phenomenon of two-photon absorption can occur, resulting in a situation where the emission wavelength is shorter than the absorption wavelength.
