A model of Single Molecule Photon Cryocooler(SMPC) was built in generally meaning. Quantum transitions in single molecule, which was excited by photons with different energy and treated as a cryocooler , were simulated with computer. Frequencies and number of phonons, which participate in thermal excitation in ground state and in excited states and during fluorescence emitting, were studied. The conclusion that single molecule in ground state has more cooling power was obtained. So in optical absorption and emission process, the thermo dynamic effect in ground state is different from that in excited state for fluorescent cooling of single molecule. So, when we choose cooling material for anti Stokes fluorescent cooling usage, splits of the energy level in ground state of luminescence center is more important than in excited state.
