## Abstract A study of vacancy‐related defects in yttrium‐doped PbWO~4~ with doping concentration of 0–1 mol% has been performed using X‐ray diffraction and positron annihilation lifetime spectroscopy. It was found that the samples have vacancy‐like defects that act as positron traps. Two main defe
