The recently available experimental data on direct photon productions from Au+Au collisions at √s_NN = 200 GeV RHIC and from Pb+Pb collisions at √s_NN = 2.76 TeV LHC energies have been analysed. The transverse momentum (p_T) distributions have been evaluated with the assumption of an initial quark gluon plasma phase at energy densities ε_i=41 and 70 GeV/fm³ with initial thermalisation times τ_i=0.2 and 1.0 fm/c respectively for RHIC and LHC energies.
