The luminescence of the natural proteins and plant pigments belong to the biological luminescence. The biological luminescences are an important branch of biological sciences. At present

the biomolecular luminescence are concentrated to the absorption of photon

the relax processes of excited state

the energy transfer and the physical processes under the action of super-short pulse laser etc.In this paper

we discussd the optic-physical processes of the chla in vivo. In addition

the spectra of the absorption

excitation and emission for the monomer

dimer and oligomer of the plant pigment are also measured. It is found that the energy levels of the triplet exciplex for the chla are lower. We also discuss the annihilation processes of aten antenna-pigments and evaluate the effective parameters of the bulk energy-transfer. At the last

we review the futures of biomolecular luminescence and some possibilition for their applications.
