Photostimulated long-lasting phosphorescence in rare-earth-doped glasses
Tb3+-doped glass sample emits bright and long-lasting phosphorescence after irradiation by an 800-nm femtosecond pulsed laser. Long-lasting phosphorescence is observed once again after further excitation by 365-nm UV light when the femtosecond laser-induced long-lasting phosphorescence cannot be detected.
