The influence of Mg doping in α-AlO crystals is investigated in this article by first-principles calculations and formation energies, density of states, and computed absorption spectra. Three models related to Mg substituting for Al doping structures were constructed, as well as spinel structure models with varying aluminum-magnesium ratios. The formation energy calculations confirmed the rationality of the MgV model, which means that Mg substitutional doping incorporating oxygen vacancies is most likely to form in crystals.

The uneven energy response of radiation detectors severely limits the accuracy of the dose rate meter used for radiation protection. Currently widely used in dose rate meters as a physical method of setting shielding compensation, the energy response correction error of the detector at different energies is mostly between 15 and 25%. This work designs a real-time correction method for energy response based on a novel CsCuI:Tl scintillation detector to improve the accuracy of the dose rate meter used for radiation protection.

- Researchers have developed a new Cs Cu I :Mn single-crystal scintillator that delivers an incredibly high light yield of approximately 95,772 photons per MeV and a fast scintillation decay time of just 3 ns.
- The scintillator's performance is significantly enhanced through micro-doping with manganese, which alters the luminescence kinetics and drastically shortens the decay time compared to previous materials.
- This newly found scintillator exhibits excellent energy resolution and offers low-cost advantages, making it a promising option for practical applications and potential commercialization in scintillation detection.
