Deep-level transient spectroscopy is like looking for special creatures hiding inside blocks. Imagine you have a big pile of blocks, but inside some of those blocks, there are tiny creatures. These creatures are really important because they can help us understand how the blocks work.
So, how do we find these hidden creatures? We use a special machine called a spectroscopy machine. This machine can look inside the blocks and see if there are any creatures hiding there.
The machine sends tiny electric pulses into the blocks and watches how they react. If there are creatures hiding inside, the pulses will make them come out and dance around a little bit. The spectroscopy machine can then see how the creatures move and figure out what kind of creatures they are.
Scientists use deep-level transient spectroscopy to understand how materials work. By finding these hidden creatures inside the blocks, they can learn how to make the blocks better or fix them if they are broken.
