本論文使用中溫水熱法合成含有不同比例之Eu3+和Tb3+組成配位中心以及1, 4-cyclohexanedicarboxylate (C8H10O4, CHDC)組成的配位聚合物，表示為R2(CHDC)3。合成之晶體以單晶及粉末X光繞射鑑定其結構及純度，感應耦合電漿原子發射光譜分析儀(ICP-AES)可以定量其不同配位中心之比例。本論文主要利用光致放光光譜、激發光譜及時間解析光譜再探討EuxTb2-x(CHDC)3一系列樣品的能量轉移機制與速率。由光譜分析確認了EuxTb2-x(CHDC)3樣品中，Tb3+傳遞能量給Eu3+是以上能階轉移的機制傳遞能量。本論文參考EuxTb2-x(CHDC)3之Eu3+訊號上升時間資訊後，對不同激發波長之Tb3+放光衰退時間進行動力學模型的分析，藉由分析數據得到能量轉移速率常數與相關物理參數，發現其Tb3+- Tb3+之能量轉移速率有極值，並成功地解釋Tb3+→Eu3+之能量轉移效率。

This work adopted the mid-temperature hydrothermal method to synthesize the coordination polymers with different compositions of Eu3+ and Tb3+ as the coordination center and 1,4-cyclohexanedicarboxylate (C8H10O4, CHDC) as the ligands. Their structure and purity were verified by single crystal and powder X-ray diffraction data and the exact composition of Eu3+ and Tb3+ was determined by the Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). Photoluminescence, excitation, and time-resolved spectra of these EuxTb2-x(CHDC)3 compounds were obtained for re-investigating the energy transfer mechanisms and rates. The analysis of spectroscopic data indicates that the energy transfer from Tb3+ to Eu3+ is an upper state energy migration instead of photon energy transfer process. Moreover, the emission decay curves of Tb3+ and the rising curves of Eu3+ at different excitation wavelengths were acquired and analyzed by kinetics models. These results show there is a concentration limitation for energy transfer efficiency and our model successfully explains the observed Tb3+→Eu3+ relative energy transfer efficiency.
