In this study, Eu3+ was evenly distributed within the glass and participated the ionic O2- and Eu3+ bond formation. Due to its strong electronegativity , it is difficult for electron transfer from ligand O2- to Eu3+, thus it requires a near ultraviolet excitation (280 nm) with higher energy level. |

電荷遷移態(tài)強(qiáng)烈 依賴于 Eu-O鍵長,隨著鍵長 的變化,鍵長越長,電荷傳遞態(tài)的 能量越低。而在本實驗中 Eu3+離子 均勻地分布于 玻璃內(nèi)部 參與了 玻璃結(jié)構(gòu) 組成,與玻璃中 非橋氧鍵中 的O2-離子 形成Eu3+-O鍵,而氧的 電負(fù)性較大,受激發(fā)時 電子從 配體O2- 轉(zhuǎn)移到 Eu3+的 難度較大,所需激發(fā)波長 在 近紫外波段 的280nm附近。 Charge transfer state is closely related to Eu-O bond length. Specifically the longger the Eu-O bond length is, the lower the charge transfer state energy will be. In this test, Eu3+ was evenly distributed inside of glass, acting as a component of glass structure and coupling with O2- of non-bridging oxygen into Eu3+-O bond. As oxygen has a larger electronegativity, which makes it difficult for excited electronics to transfer from ligand O2 - to Eu3+, therefore the required excitation wavelength should be located around 280nm of near ultraviolet waveband. |
