Abstract
is about 2.15 eV at 80 K, which is in good agreement with the experimental results. It is confirmed that temperature-dependent PL is composed of a band-edge exciton state and trapping state emission. The results obtained will be of certain significance to further expand other hybrid organometal perovskite materials.
