White Light Emission and Enhanced Color Stability in a Single-Component Host.

Eu ion can be effectively sensitized by Ce ion through an energy-transfer chain of Ce-(Tb) -Eu, which has contributed to the development of white light-emitting diodes (WLEDs) as it can favor more efficient red phosphors. However, simply serving for WLEDs as one of the multicomponents, the design of the Ce-(Tb) -Eu energy transfer is undoubtedly underused. Theoretically, white light can be achieved with extra blue and green emissions released from Ce and Tb.

Tunable Magnetization Dynamics through Solid-State Ligand Substitution Reaction.

The dimeric molecule [Dy(acac)(MeOH)(bpe)]·bpe·2MeOH (1, acac = acetylacetonate, bpe = 1,2-bis(4-pyridyl)ethylene) undergoes a solid-state ligand substitution reaction upon heating, leading to the one-dimensional chain [Dy(acac)(bpe)] (2). This structural transformation takes advantage of the potential coordination of the guest bpe molecules present in 1. In both complexes the Dy(III) ions adopt similar octacoordinated D geometries.
