New luminescent cage-like tetranuclear silsesquioxanes [NEt][(PhSiO)(TbEu)(NO)(OH)(EtOH)(HO)]·4(EtOH) (1) and [NEt][(PhSiO)(TbEu)(NO)(EtOH)(MeCN)]·4(MeCN) (2) present a tunable thermosensitive Tb-to-Eu energy transfer driven by Tb and Eu emission and may be used as temperature sensors operating in the range 41-100 °C with excellent linearity ( = 0.9990) and repeatability (>95%). The thermometer performance was evidenced by the maximum relative sensitivity of 0.63% °C achieved at 68 °C.
新型发光笼状四核倍半硅氧烷[NEt₄][(PhSiO₁.₅)₈(Tb₂Eu₂)(NO₃)₂(OH)₂(EtOH)₂(H₂O)₂]·4(EtOH) (1)和[NEt₄][(PhSiO₁.₅)₈(Tb₂Eu₂)(NO₃)₂(EtOH)₂(MeCN)₂]·4(MeCN) (2)呈现出由Tb和Eu发射驱动的可调谐热敏Tb到Eu能量转移,并且可用作在41 - 100 °C范围内运行的温度传感器,具有出色的线性度(相关系数 = 0.9990)和可重复性(>95%)。在68 °C时实现的最大相对灵敏度为0.63% °C,证明了其温度计性能。
