The 1988 Parma Conference carries on the tradition of International Conferences, which originated as a meeting on Color Centers in Alkali Halides in 1956. Over the years the meeting has developed into the International Conference on Defects in Insulating Crystals. This year it will focus on the current state of knowledge of defects and defect processes in a wide range of materials. It will bring together scientists from both academic institutions and industry and will present a unique opportunity for discussion of the role of defects in modern material technology. The Conference will stress the value of a fundamental scientific understanding of defects in the design and application of materials for specific purposes. Defects, Crystals.
