Simultaneous TL and TSEE measurements were carried out with Li2B4O7 glass ceramics in which Cu+ had been implanted and glass ceramics which were made of (Li2B4O7:Cu+SiO2+Pt). For all cases it was found that the TSEE responses were stable and reliable. However, the TL response of the Cu+-implanted samples showed a very unstable behavior, probably because the implanted Cu+ could not find stable sites in crystals under the heat treatment condition adopted in this experiment. It was also found that (Li2B4O7:Cu+SiO2+Pt) glass ceramics had good TL and TSEE responses as solid-state dosemeters.
