The electronic absorption, resonance Raman (RR) and time-resovled resonance Raman (TR3) spectra of the monomerc and dimeric complexes of ruthenium (II) with 2,3-bis(2-pyridyl) pyrazine(dpp) were measured, I.e. Ru(bpy)2 dpp2+ and Ru(bpy)2dpp Ru(bpy)24+, where bpy is 2,2'-bipyridine. In addition, in order to facilitate definitive assignments of the observed RR spectral parameters, the corresponding selectively labeled complexes employing perdeuterated bpy (d8BPY) were also prepared and studied.It is shown that using judiciously chosen excitation lines to acquire the RR spectra permits selective enhancement of vibrational featrres associated with specific molecular fragmengts of the complexes, facilitating structural characterization of ground states of each complex. In addition, the TR3 spectrum of the monomeric complex yields vibrational signatures of its 3MLCT state, which is consistent with polarization of electron density to wards the pyrazyl fragment; corresponding studies of the dimeric complex failed to provide conclusive evidence for modes attributable to an anion radical fragment, presumably owing to lack of effective enhancement with the excitation lines available.

This report documents the spectroscopic and photophysical properties of the complexes, Ru(bpdz)32+ and [Ru(bpy)2(bpdz)]2+, where bpdz=3,3'-bipyridazine and bpy=2,2'-bipyridine Specifically, the complexes were characterized by UV-visible, emission, resonance Raman(RR), and transient resonance Raman (TR3) spectroscopic data, as well as lifetime measurements. The RR spectrum of the Ru(bpdz)32+ complex documents the characteristic modes of the coordinated ligand, whereas the RR spectra of the heteroleptic complex, [Ru(bpy)2(bpdz)]2+, obtained at judiciously chosen excitation wavelengths, reveal aelective enhancement of eithe bpy modes or bpdz modes, depending upon the particular excitation wavelength, permitting difinitive assignment of the observed, electronic absorption bands and establishing the lowest energy electroic transition as having a Ru-to-bpdz charge-transfer character. The TR3 spectrum of the Ru(bpdz)32+ complex reveals the characteristic frequencies of the coordinated bpdz-* anion radical, as expected, whereas corresponding studies of the heteroleptic com plex, [Ru(bpy)2(bpdz)]2+, reveal thee characteristic bpdz-* modes in the absence of any modes attributable to bpy-* anion radicals, providing difinitive evidence for the [Ru(III)(bpy)2(bpdz-*)]2+ formulation of the excited state of this com plex, Lifetime measurements for both com plexes, made over a wide, range of temperatures and interpreted with a model derived from previous measurements made on a large number of similar complexes, indicate that the two complexes of interest decay by different nonradiative pathways resulting from thermal population of a ligand field3dd and/or a lower lying 4th 3 MLCT state.

Ustng the Bridgeman-Stockbarger method, the KMgF3: Eu2+ single crystal was growen. The color centers in umirradiated KMgF3: Eu crystal were studied. By thermal annealing, we confirmed the 422-nm emission resulted from color centers and oxygen centers, and we proved the energy transfer from Eu2+ to color centers. From spectra, the relative oxygen content in crystal was calculated, and the relationships of oxygen displacing fluorine were studied.

Energy transfer processes between Eu2+ and GD3, CR3+, Ce3+ ions in KMgF3 which are difficult to study spectro-scopically, have been investigated by using the proposed four-level decay model of the 6P7/2 escited state of the Eu2+ ion. GD3+ AND Ce3+ transfer its energy to the vibronic transition of the 6P7/2→S7/2 transition of Eu2+, whereas Cr3+ receive energy from Eu2+ 4f65d level to the Ce3+ 4f5d state is observed spectroscopically, and the energy transfer mechanism is discussed.

测定了一系列单掺杂Eu2+和双掺发Eu,X(X=Ce,Gd,Cu)的KMgF3晶体在300K和77K的高分辨发射光谱以及伴随的振动光变,据此研究了Eu2+在这些体系中的振动跃迁特征,并指认了每一振动峰所对应的正则振动模式。首次发现了在共掺杂体系中Eu2+振动频率与其它掺杂离子格位取代间的相关性。

【期刊论文】Four-Level Decay Model of 6P7/2 Excited State of Eu2+ Ion in KMgF3

A four-level decay model of 6P7/2 excited state of Eu2+ ion in KMgF3: Eu2+ has been proposed. The decay profiles of the 6P7/2 excited state of Eu2+ are two exponential and the physical implication of each term in the fit equation responsible for the model is inerpreted. The data obtained spectroscopically are in good agreemet with the fit results.

用传统的高温固相法及近几年兴起的温和水热法合成了KMgF3: Eu多晶粉末,同时用BndgЙаЛSlockbarger法生长了KMgF3: Eu单晶体。对三种方法合成的样品进行比较发现:水热和单晶体样品中,除了Eu2-的 f-f 锐线发射外,还观察到了420nm处的宽带发射;这些发射带主要应归属于晶体中存在的色心和氧中心。而且与高温样品相比,Eu2-在360nm处的线发射强度明显减小,原因是发生了Eu2-到色心的能量传递。
