Development of bismuth-based persistent phosphors with wavelength tunability

为了揭示Bi掺杂的荧光粉中发光激发态的起源，成功地介绍了一种新的方法，并证明了CaMO 3：Bi 3+（M= Zr，Sn，Ti）钙钛矿族（M.上田，徐，K.阿萨米湖Amidani，E. Trave，S.田边，物理化学杂志C 2019，123，14677-14688）。 此外，在玻尔兹曼测温领域，（i）我们实验和理论上证明了Cr 3+激活材料相对于用于生物传感的现有技术的Nd 3+和Er 3+温度计的上级性能（M.回来，J.上田，M.G. Brik，T. Lesniewski，M.

With the aim to disclose the origin of the luminescent excited states in Bi-doped phosphors, a new methodology was successfully introduced and proved for the CaMO3: Bi3+ (M= Zr, Sn, Ti) perovskite family (M. Back, J. Ueda, J. Xu, K. Asami, L. Amidani, E. Trave, S. Tanabe, J. Phys. Chem. C 2019, 123, 14677-14688). Moreover, in the field of Boltzmann thermometry, (i) we experimentally and theoretically demonstrated the superior performances of Cr3+-activated materials with respect to the state of the art Nd3+ and Er3+ thermometers for biological sensing (M. Back, J. Ueda, M.G. Brik, T. Lesniewski, M. Grinberg, S. Tanabe, ACS Appl. Mater. Interfaces 2018, 10, 41512-41524; M. Back, J. Ueda, J. Xu, K. Asami, M. G. Brik, S. Tanabe, Adv. Opt. Mater. 2020, 4, 2000124(1-10); J. Ueda, M. Back, M. G. Brik, Y. Zhuang, M. Grinberg, S. Tanabe, Opt. Mater. 2018, 85, 510-516) and (ii) we proposed a new concept based on the use of the tunable phase transition of Gd, Nd-codoped LaGaO3 perovskites as customized phase-transition based ratiometric optical thermometers for the self-control of specific temperatures (M. Back, J. Ueda, J. Xu, D. Murata, M. G. Brik, S. Tanabe, ACS Appl. Mater. Interfaces 2019, 11, 38937-38945).
