We detected spatially extended Ly$\\alpha$ emission envelopes surrounding these six quasars, with projected spatial extent in the range 26 $\\le$ $d_{\\rm Ly\\alpha}$ $\\le$ 51 kpc. No correlation is found between the quasar ionizing luminosity and the Ly$\\alpha$ luminosity of their extended envelopes.
