Sh. Chen et U. Nickel, CONTROLLABLE EXCITON BLEACHING AND RECOVERY OBSERVED IN ZNO-AG HYBRIDNANOMETER-SIZED PARTICLES, Chemical communications, (2), 1996, pp. 133-134
Damping of the exciton absorption band of deaerated ZnO sol is directl
y related to the amount of silver photochemically deposited on the ZnO
surface; recovery of this exciton band is achieved after the solution
is exposed to air and silver oxide is formed.
