我们结合实验和理论分析了金属纳米颗粒在绝缘支架上的核心能级结合能（BE）随粒径的变化，表明这些变化在很大程度上是由晶格应变引起的。BE班次的这种贡献以前没有被认识到。晶格应变改变了金属原子之间的化学键，这种变化引起BE位移。
Our combined experimental and theoretical analysis of the shifts, with particle size, of core-level binding energies (BE's) of metal nanoparticles on insulating supports, shows that these shifts have an important initial state contribution arising, in large part, because of lattice strain. This contribution of BE shifts has not been recognized previously. Lattice strain changes the chemical bonding between the metal atoms and this change induces BE shifts.
