Abstract
⺠Luminescence properties of the washed and unwashed ZnO nanoparticles are different. ⺠It is explained in terms of the dissimilar nature of the surface charge polarity. ⺠Zeta potential study shows that the intrinsic surface of ZnO nanoparticles have negative polarity. ⺠Hydroxyl groups are found to be the primary cause for GL emission for these ZnO nanoparticles. ⺠The origin for the remnant GL emission which survives the evacuation is found to be different.
