AI Technical Summary

Technical Problem

The complex single-crystal growth process of traditional inorganic scintillators leads to high costs and limitations in flexible imaging applications. The self-absorption caused by the small Stokes shift in two-dimensional perovskite materials hinders the improvement of photoluminescence quantum yield and light yield, thus limiting their development in scintillator applications.

Method used

By using Mn2+-doped two-dimensional hybrid perovskite materials, new luminescent centers are introduced through a simple synthesis method, which enhances photoluminescence performance, reduces self-absorption, and increases light yield.

Benefits of technology

We have developed a low-cost, highly stable, and excellent scintillation-performance manganese-doped two-dimensional hybrid perovskite material suitable for photodetectors, photovoltaic devices, field-effect transistors, light-emitting diodes, and scintillation imaging.
