摘要:
在水热法合成羟基磷灰石颗粒(Hydroxyapatite,HAp)的过程中加入碲化镉(CdTe)量子点前体,合成可激发出红色荧光的羟基磷灰石/碲化镉(HAp/CdTe)荧光探针,对所得荧光探针的形貌、大小和荧光特性进行表征,并探究其在铜离子检测领域应用的可行性。结果表明:所得HAp/CdTe荧光探针为针状实心颗粒,长径约为350 nm,短径约为80 nm;HAp/CdTe荧光探荧光强度较高、发射光谱范围较窄和其荧光强度有良好的pH和温度稳定性;在用于铜离子检测方面,铜含量为1.3~51.2 mg/L范围内,探针的荧光强度变化与Cu2+浓度之间呈现出良好的线性关系,相关系数为0.9986,检测限为0.4 mg/L,且其他离子(Na+、Mg2+、Ca2+、Li+、NH4+、K+和Cd2+)对该检测方法无明显干扰作用。合成的HAp/CdTe荧光探针具有制备方法简单、成本较低、荧光性质稳定和可长期保存的特点,是作为检测铜离子浓度的理想材料。
