Traditionally the deformation resistance in creep.is characterized by the minimum creep.rate εmin and its sensitivity to stress （stress exp.nent n） and temp.rature （activation energy Q）. Various values of constant n have been rep.rted in the literature and interp.eted in terms of sp.cific mechanisms. The p.esent case study of coarse-grained Cu at 573 K yields a stress exp.nent n = 9 for εmin. in tension and a relatively low activation energy. The evolution of the deformation resistance with strain at constant tensile creep.load and comp.rison with creep.in comp.ession without fracture indicates that the tensile εmin. result from transition from uniform deformation to strain localization during fracture. This is confirmed by the results of creep.in comp.ession where fracture is sup.ressed. Both the tensile εmin, and the comp.essive creep.rate at strains around 0.3 can be described using existing equations for quasi-stationary deformation containing the subgrain boundary misorientation θ as structure p.rameter. While in the latter case constant θ leads to monotonic increase of n with stress, the tensile nine-p.wer-law results from variable θ, and has no simp.e meaning. The result of this case study means that uncritical interp.etation of minimum tensile creep.rates as stationary ones bears a high risk of systematic errors in the determination of creep.p.rameters and identification of creep.mechanisms.

To break through the bottle-neck of quantum yield in up.onversion （UC） core-shell system, we elucidated that the energy transfer efficiency in core-shell system had an evident contribution from the charge transfer of interface with related to two factors：（i） band offsets and （2） binding energy area density. These two variables were determined by material intrinsic p.op.rties and core-shell thickness ratio. We further unraveled the mechanism of non-radiative energy transfer by charge transfer induced dip.le at the inter- face, based on a quasi-classical derivation from F6rster typ. resonant energy transfer （FRET） model. With stable bonding across the interface, the contributions on energy transfer in both radiative and non-radiative energy transfer should also be accounted together in Auzel＇s energy transfer （ETU） model in core-shell system. Based on the discussion about interface bonding, band offsets, and forma- tion energies, we figured out the significance of interface bonding induced gap.states （IBIGS） that p.ayed a significant role for influ- encing the charge transfer and radiative typ. energy transfer. The interface band offsets were a key factor in dominating the non-radiative energy transfer, which was also correlated to core-shell thickness ratio. We found that the energy area density with re- lated to core/shell thickness ratio followed the trend of Boltzman sigmoidal growth function. By the p.ysical trend, this work contrib- uted a reference how the multi-layered core-shell structure was formed starting from the very beginning within minimum size. A route was p.ved towards a systematic study of the interface to unveil the energy transfer mechanism in core-shell systems.
