Problems solved by technology

These provide strong support for the application of Bi-doped materials in the mid-infrared, but there are also some shortcomings. For example, the above phenomena are mostly observed at low temperatures, and the Bi 5 (AlCl 4 ) 3 Although the above-mentioned materials have mid-infrared luminescence at room temperature, because the preparation temperature of the materials is very low (less than 350°C), the stability and processing performance are relatively poor, so the practicability of the above materials is still relatively lacking.
