text: site for synthesis of zns nanocrystals using zno? it 'must' use zno or dimethyl zinc as precursor convert zno to the nitrate.  zno + hno3 -> zn(no3)2 + h2o  treat zn(no3)2 with h2s slowly, slowly stir the soln to get a suspension of zns.  transform it into a colloid and then destabilise it slowly.
