We study the scenario that a newborn strange quark star cools to the quantum chromodynamics (QCD) phase transition temperature and converts to a neutron star, and we calculate the evolution of temperature and luminosity of the compact star. We argue that the conversion energy released can be of the order of 1053 erg. We also propose that a second neutrino burst will be emitted at the completion of this phase transition.
