source:ACS PublicationsRare earth (RE)-based complexes, due to their unique electronic structures, exhibit excellent fluorescence properties with high quantum yield and a long lifetime. From an application perspective, exploring RE-based complexes in luminescent optoelectronic devices asks for effective modulation approaches that control the luminescent properties. Here we report an electrically modulated fluorescence phenomenon in an RE-based complex, namely Eu16(μ4-F)6(μ3-F)12(tBuCOO)18[N(CH2CH2O)3]4 (EuFC-16) particles, which effectively controls the optical behavior of individual particles...

Octupole excitation: Research provides direct evidence for rare, pulsing pear shapes in gadolinium nuclei source:University of SurreyFor the first time, scientists have acquired direct evidence of rare, pulsing pear-shaped structures within atomic nuclei of the rare-earth element gadolinium, thanks to new research led by the University of Surrey, the National Physical Laboratory (NPL) and the IFIN-HH research institute in Bucharest, Romania.The study, published in Physical Review Letters, provides definitive proof of a strong collective "octupole excitation" in the nucleus of ga...
