The adsorption of silica nanoparticles onto representative mineral surfaces and at the decane/water interface was studied. The effects of particle size (the mean diameters from 5 to 75 nm), concentration and surface type on the adsorption w...
Passivation of lanthanide surface sites in sub-10 nm NaYF(4):Eu(3+) nanocrystals [0.03%]
亚10nm NaYF4:Eu3+纳米晶体中镧系表面位点的钝化
