Precision crystal calorimeters traditionally
play an important role in high energy physics experiments. In the last two
decades, it faces a challenge to maintain its precision in a hostile radiation
environment. This paper reviews the performance of crystal calorimeters
constructed for high energy physics experiments and the progress
achieved in understanding crystal's radiation damage as well as in developing
high quality scintillating crystals for particle physics. Potential
applications of new generation scintillating crystals of high density and high
light yield, such as LSO and LYSO, in particle physics experiments is also
discussed.
