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).

Mater. 2018, 85, 510-516) and (ii)我们提出了一个新概念，该概念是基于使用GD，ND编码的Lagao3 Perovskites的可调相过渡作为基于定制的相变的定制相变的特定温度自我控制的基于定制的相变光度计（M. Back，J。Ueda，J.Ueda，J.Ueda，J.Xu，D。Murata，D。Murata，M。Brik，S。Brik，S。Tanabe，Acs。 38937-38945）。
