以Ln 3+（Ln=Nd，Yb）离子和1，3，5-苯三甲酸（H3 BTC）为原料，采用简单的溶剂热法制备了近红外发光MOFs温度计（Nd 0. 676 Yb 0. 324 BTC），并用PXRD、TGA、ICP和光致发光（PL）光谱对其进行了表征。这些结果表明，Nd 0.676 Yb 0.324 BTC在生理温度范围内（288-323 K）表现出高的相对灵敏度和良好的重复性，在323 K时的最大相对灵敏度为1.187% K− 1。这些近红外发光MOFs在生理温度传感方面具有潜在的应用。
A near infrared luminescent MOFs thermometer (Nd0.676Yb0.324BTC) was prepared via a simple solvothermal method using Ln3+(Ln=Nd, Yb) ions and 1, 3, 5-benznenetricarboxylic acid (H3BTC), and characterized by PXRD, TGA, ICP, and photoluminescence (PL) spectrum. These results indicate that the Nd0.676Yb0.324BTC displays high relative sensitivity and excellent repeatability in the physiological temperature range (288–323 K), and the maximum relative sensitivity is determined to be 1.187% K−1at 323 K. These NIR luminescent MOFs may have potential applications in physiological temperature sensing.
