通过后修饰的方法制备新的杂化物被认为是开发新一代高灵敏度和高选择性化学传感器的直接策略。本文报道了用咪唑骨架8（ZIF-8）分子筛对Zn 2GeO 4：Mn 2+纳米棒进行表面修饰制备的复合化学传感器。发光研究表明，Zn 2GeO 4：Mn 2 +@ZIF-8异质结构在298 ~ 423 K温度范围内，Cu 2+浓度在1 × 10− 4 ~ 1 × 10− 1 mol·L−1范围内具有良好的温度敏感性能。这些结果使得Zn 2GeO 4：Mn 2 +@ZIF-8复合材料成为温度计和金属离子检测中发光应用的极好候选者。
Facile fabrication of new hybrids by post-modification approach is considered to be a straight forward strategy to develop new generation of chemosensor with high sensitivity and selectivity. In this work, a hybrid chemosensor prepared through surface modification of Zn2GeO4:Mn2+nanorods by zeolitic imidazolate framework-8 (ZIF-8) is reported. Luminescent investigations revealed that the as-prepared Zn2GeO4:Mn2+@ZIF-8 heterostructure featured excellent sensing function with respect to temperature change from 298 K to 423 K, and Cu2+ions concentration from 1 × 10−4mol·L−1to 1 × 10−1mol·L−1. These results make Zn2GeO4:Mn2+@ZIF-8 composite superb candidate for luminescent applications in thermometers and metal ions detection.
