This paper studied the effects of cations and polymer matrix on the fluorescent properties of quantum dots (QDs). The results indicated that temperature has a greater impact on fluorescence intensity than clay cations (mainly K+ and Na+). Combined fluorescence lifetime and steady‐state spectrometer tests showed that QD lifetimes all decreased when the cation concentration was increased, but the quantum...
Two new ternary tetrazolate Eu(III) complexes with phosphine oxide co‐ligands Eu(PTO)3·(P1/P2) [PTO = 5‐(2‐pyridyl‐1‐oxide)tetrazole, P1 = diphenylphosphorylamino‐phenylphosphoryl‐benzene, P2 = diphenylphosphorylpyridine)‐bis‐isobutyricphosphoryl] were synthesized and characterized using UV, fluorescence, IR and 1H NMR spectroscopic techniques. The analytical data prove that the complexes are mononuclear...
