An international collaborative research project to investigate the preparation and properties of quantum dot materials based on CdS microcrystals in various matrices has been carried out form July 1991 To May 1994. The team consisted of Professor J.D. Mackenzie P.I., Professor M. Yamane of the Tokyo Institute of Technology, and Professor N. Peyghambarian of the University of Arizona. Samples were prepared by the Sol-Gel method with sodium borosilicate glass and ormosils organically modified silicates as the matrices. The samples showed no photodarkening effect and have chi cubed values up to 10exp -6 cgs units. Techniques were developed to limit the size distribution of the Cds while maintaining high concentrations -10. Waveguides were fabricated by the ion- exchange method. At their present developmental stages, the samples suggested the possibility that they can be made into a new type of lasers and also offer the potentials of achieving photochemical hole-burning at room temperature.
