目的研究氯化苯并咪唑镨配合物的光致发光性质。方法在氙灯的激发下,测量了浓度为1×10-4mol/L氯化苯并咪唑镨配合物水溶液的三维荧光激发和发射光谱,并讨论了该配合物的升频转换荧光现象及其机制。结果氯化苯并咪唑镨配合物具有优良的光致发光特性。结论Pr3+离子对配体苯并咪唑具有荧光增敏作用。
Aim To study the photoluminescence properties of benzimidazolium praseodymium chloride complexes. Methods Three-dimensional fluorescence excitation and emission spectra of the aqueous solution of benzimidazole praseodymium chloride at a concentration of 1 × 10-4 mol / L were measured under xenon lamp excitation. The up-conversion fluorescence phenomenon and its mechanism of the complex were also discussed . Results The benzimidazolium praseodymium chloride complex has excellent photoluminescence properties. Conclusion The Pr3 + ion has a sensitizing effect on the benzimidazole ligand.
