Abstract

The formation of trimetallic terbium-europium-gadolinium complexes was proposed as an approach to increase the sensitivity of the corresponding terbium-europium complexes for temperature measurement due to the suppression of multiphotonic emission. This approach results in over a 2-fold increase of the sensitivity of Eu-Tb carboxylate, which reached 5.3% K-1 in the physiological range.

摘要

提出了形成三金属铽-铕-钆配合物的方法，以增加相应铽-铕配合物对温度测量的灵敏度，因为这种方法抑制了多光子发射。这种方法使 Eu-Tb 羧酸盐的灵敏度提高了一倍以上，在生理范围内达到了 5.3% K-1。
