Cooperative Energy

The concentration luminescence quenching of the NIR emission of Yb3+ in nanocrystalline ZrO2 is studied. It is found that the quenching is dominated by cooperative energy transfer processes from isolated Yb3+ ions to Yb-Yb pairs (Yb dimers). The Yb dimer concentration depends on the crystallite phase and size, which on time depends on Yb concentration. An extended energy transfer model was developed to predict the IR and cooperative visible fluorescence emissions by taking in to account the crystalline phase, the nanocrystals size, and the geometrical construction of Yb dimers. Our model succeeds to fit simultaneously both experimental VIS and NIR emissions, and the corresponding interaction parameters are reported.

Energy Transfer Model

To improve the accuracy of quartz crystal microbalance (QCM) immunosensor, it is the key to distinguish accurately and effectively about the effects of mass loading and damping loading of a quartz resonator vibrating in damping environment. The energy transfer model (ETM) is introduced to deduce functional relationship between the product of absolute viscosity and density of the liquid deposit and the maximum amplitude of vibration at the quartz-resonator surface. Then the effect of mass loading can be rapidly distinguished from damping loading by measuring the frequency shift and the amplitude of QCM. This method provides a new theoretical basis for the application of QCM immunosensor in medical diagnosis, especially in tumor diagnosis.
