为了揭示掺铋发光材料中发光激发态的起源，成功地提出并证明了一种新的钙钛矿型钙钛矿系列发光材料(M.Back，J.Ueda，J.Xu，K.Asami，L.Amidani，E.Trave，S.Tanabe，J.Phys)的研究方法。化学。C 2019年、第123、14677-14688)。此外，在玻尔兹曼测温领域，(I)我们从实验和理论上证明了与用于生物传感的最先进的ND3和Er3温度计(M.Back，J.Ueda，M.G.Brik，T.Lesniewski，M.Grinberg，S.Tanabe，ACS Appl.)相比，Cr3激活材料具有优越的性能。马特。接口2018年，10,41512-41524；M.Back，J.Ueda，J.Xu，K.Asami，M.G.Brik，S.Tanabe，Adv.Opt.马特。2020年，4,2000124(1-10)；J.Ueda，M.Back，M.G.Brik，Y.Zang，M.Grinberg，S.Tanabe，Opt.马特。2018，85,510-516)和(Ii)我们提出了一种新的概念，该概念基于Gd，Nd共掺钙钛矿的可调谐相变作为定制的基于相变的比率光学温度计(M.Back，J.Ueda，J.Xu，D.Murata，M.G.Brik，S.Tanabe，ACS Appl)。马特。接口2019、11、38937-38945)。

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).
