Photoluminescence in quasi-amorphous Pb0.8X0.2Zr0.53Ti0.47O3 (X=Ca, Sr and Ba) powders: An optical and structural study

Photoluminescence properties and synthesis of a PZT mesostructure obtained by the microwave-assisted hydrothermal method

“…The PL spectroscopy is an effective way to investigate the electronic structure as well as the optical properties of semiconductor materials [17]. Important information such as surface defects, oxygen vacancies, surface states, photo-induced charge carrier separation and a recombination process in nano-size semiconductor materials can be obtained from PL spectroscopy.…”
