摘要：

Based on an R-band imaging survey of six high-redshift (z similar to 2) and high-luminosity (M(B) less than or similar to - 28 mag) QSOs, we report the detection of extensions in two radio-quiet and one radio-loud QSO. The extensions are most likely due to the host galaxies of these QSOs, with luminosities of at least 3-7 per cent of the QSO luminosity. The most likely values for the luminosities of the host galaxies lie in the range 6-18 per cent of the QSO luminosities.
