从位于硅纳米粒子中的光激发激子到吸附的氧分子的能量转移将它们激发到反应性单线自旋态。该过程已作为纳米颗粒尺寸的函数进行了实验研究，并应用外部磁场作为对纳米硅激子与吸附的 O2 分子之间交换耦合这一过程的公认理解的测试。
Energy transfer from photoexcited excitons localized in silicon nanoparticles to adsorbed oxygen molecules excites them to the reactive singlet spin state. This process has been studied experimentally as a function of nanoparticle size and applied external magnetic field as a test of the accepted understanding of this process in terms of the exchange coupling between the nano-Si exciton and the adsorbed O2 molecules.
