Herein, high-quality centimeter-scale 2D Bi2O2Se films tend to be successfully synthesized to reveal the lattice characteristics and dielectric features underneath the control of depth and temperature. It was demonstrated that the stronger electrostatic Bi-Se interactions result in a stiffened phonon vibration of thicker Bi2O2Se layers. Three excitons (Ea, Eb, and Ec) show significant red changes with level stacking. Interestingly, the dielectric properties within the v
