The coming era of large photometric wide-field surveys will increase the detection rate of supernovae by orders of magnitude .
Such numbers will restrict spectroscopic follow-up in the vast majority of cases , and hence new methods based solely on photometric data must be developed .
Here , we construct a complete Hubble diagram of Type II supernovae combining data from three different samples : the Carnegie Supernova Project-I , the Sloan Digital Sky Survey-II SN , and the Supernova Legacy Survey .
Applying the Photometric Colour Method ( PCM ) to 73 Type II supernovae ( SNe II ) with a redshift range of 0.01–0.5 and with no spectral information , we derive an intrinsic dispersion of 0.35 mag .
A comparison with the Standard Candle Method ( SCM ) using 61 SNe II is also performed and an intrinsic dispersion in the Hubble diagram of 0.27 mag is derived , i.e. , 13 % in distance uncertainties .
Due to the lack of good statistics at higher redshifts for both methods , only weak constraints on the cosmological parameters are obtained .
However , assuming a flat Universe and using the PCM , we derive a Universe ’ s matter density : \Omega _ { m } =0.32 ^ { +0.30 } _ { -0.21 } providing a new independent evidence for dark energy at the level of two sigma .
