力致发光材料因其具有外力作用诱导产生发光的独特性质，其在冲击力、应力、张力或压力等作用力的传感，以及显示、照明、成像等领域具有巨大应用潜力，近年来引起了人们广泛关注。实验以二苯甲酰甲烷(DBM)、Eu(NO₃)₃和三乙胺(TEA)为原料，通过共沉淀法快速合成了离子型Eu³⁺配合物Eu(DBM)₄TEA。采用紫外-可见吸收光谱、红外吸收光谱和X射线衍射谱对配合物的结构进行表征，并测定配合物的荧光性质和力致发光性能。本实验是在现有科研成果的基础上开发的包含稀土金属有机配合物合成、产物仪器表征和产物性能模块化综合化学实验，实现了科教融合；实验原料廉价、实验操作简单，模块化的设计机动灵活，能满足基础实验、综合实验和趣味科普实验等不同层次本科教学需求；实验现象可视，有助于激发学生学习兴趣，提升学生专业认同感。

Hydroxyapatite nanoparticles (HAP NPs) were synthesized by a one‐step hydrothermal method. The surface of HAP NPs was grafted —SH and —COOH chelating groups via in situ surface‐modification with iminodiacetic acid (IDA) and 3‐mercaptopropyl trimethoxysilane (MPS) to afford dual surface‐capped nano‐amendment HAP‐IDA/MPS. The structure of HAP‐IDA/MPS was characterized, and its adsorption performance for Hg²⁺, Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, and Cd²⁺ was evaluated. The total adsorption capacity of 0.10 g HAP‐IDA/MPS nano‐amendment for Hg²⁺, Cu²⁺, Zn²⁺, Ni²⁺, Co²⁺, and Cd²⁺ with an initial mass concentration of 20 mg·L^-1 reached 13.7 mg·g^-1, about 4.3 times as much as that of HAP. Notably, HAP‐IDA/MPS nano‐amendment displayed the highest immobilization rate for Hg²⁺, possibly because of its chemical reaction with —SH to form sulfide, possessing the lowest solubility product constant among a variety of metal sulfides.
