Abstract
Yb:NaGd(WO4)2 single crystals are implanted with 6.0 MeV O ions at room temperature. The effects of ion irradiation on the structure and spectral properties are demonstrated by employing X-ray diffraction techniques, high resolution X-ray diffraction techniques and photoluminescence (PL) measurement. The corresponding results show that the sample can retain good crystallinity by irradiation at relative low fluences of 1.6 × 1014 ions/cm2, whilst both the PL intensity and the line bandwidth can be effectively improved.
