A new paradigm of sonoluminescence phenomena which displays alternating pattern of on/off luminescence pulse was observed recently in aqueous sulfuric acid solutions. A set of solutions of the Navier-Stokes equation for the gas inside a spherical bubble with heat transfer through the bubble wall permits to predict correctly characteristics of the sonoluminescing phenomena in the solutions. Calculation results of the minimum velocity of bubble wall, the peak temperature and pressure are in excellent agreement with the observed ones. Further, the calculated bubble radius-time curve displays alternating pattern of bubble motion as observed in experiment. The origin of sonoluminescence from gas bubble in sulfuric acid turns out to be blackbody emission with finite absorption.
