Anomalous optical properties of small silver particles and some silver halides are discussed as displays of critical phenomena due to particle size decreasing or to their interaction with each other in an ensemble. Special consideration is given to weak localization of conduction electrons in a small metal particle, to plasmon delocalization in ensemble of metal particles, to the effect of zero- dimensional percolation in a small dielectric particle, and to the effect of size on the superionic transition in small AgI particles and thin envelopes.
