Abstract
Coactivation of oxyorthosilicates of X2 type of the system Lu2-xYxSiO5 :Ce(y)3+ with either Sm3+ or Zr4+ introduces charge trapping defect ce ntres. These centres are able to store carriers after X-ray irradiatio n. Photostimulation and/or thermal stimulation results in radiative re laxation of the activator Ce3+. Models for the storage mechanism are s uggested.
