PVB的音标

When the ZnO nanoparticles are capped with PVB, PVB molecules do not only improve the surface of ZnO nanoparticles by compensating dangling bonds and unsaturated bonds, but also spatially block the process of surface-trapped hole tunneling back into the particles to form VO recombination center.

实验结果表明：经PVB包覆后，PVB不仅减少了ZnO纳米粒子表面的悬键和非饱和键，而且也从空间上阻断了被表面俘获的空穴遂穿回粒子内部形成VO复合中心。
