| dc.description.abstract | 本論文使用中溫水熱法合成R2(C8H10O4)3配位聚合物，其中R= Y, Eu, Tb，分別以不同莫耳比例組成配位中心，而配位基C8H10O4為1, 4-cyclohexanedicarboxylate (CHDC)。合成之晶體以單晶及粉末X光繞射鑑定其結構及純度，而配位中心的元素比例則以感應耦合電漿原子發射光譜分析儀(ICP-AES)進行確認。本論文主要針對EuxTb2-x(CHDC)3化合物進行探討，測量了一系列樣品之光致放光光譜、激發光譜及時間解析光譜。進行分析後再次確認Eu3+與Tb3+之間能量傳導會與相鄰機率有關，且發現敏化配位基CHDC會影響到Eu3+與Tb3+之間能量傳導效能。本論文對Eu3+訊號上升時間及Tb3+放光衰退時間進行動力學模型的分析，發現Eu3+與Tb3+之間是個三維能量傳導的模式，並由分析數據得到能量轉移速率常數與相關物理參數，其結果成功地解釋Tb3+→Eu3+之能量轉移效能。 | zh_TW |
| dc.description.abstract | This work adopted mid-temperature hydrothermal method to synthesize coordination polymers, R2(C8H10O4)3, (R= Eu or Tb, and C8H10O4: 1, 4-cyclohexanedicarboxylate, CHDC). Single-crystal and powder x-ray diffraction (XRD) data were collected for confirming their structure and purity. Inductively Coupled Plasma Atomic Emission Spectra (ICP-AES) were also obtained to verify the compositions of Eu3+ and Tb3+. We have acquired the photoluminescence (PL), excitation, and time-resolved spectra of several EuxTb2-x(CHDC)3 compounds. The analysis of these spectra shows that the energy transfer is indeed correlated to the contact probability between Eu3+ and Tb3+ as well as to the sensitization of CHDC ligands. Kinetics models were used to fit the rising temporal profiles of Eu3+ and the decay curves of Tb3+. The results indicate the energy transfer is three dimensional (3D). The rate constants and related parameters were successfully determined. The energy transfer efficiency can be well explained by these results. | en_US |
