The color conversion glass ceramics which were made of borosilicate matrix co-doped(SrBaSm)Si2O2N2:(Eu^3+Ce^3+) blue-green phosphors were prepared by two-step method in co-sintering. The change in luminescence properties and the drift of chromaticity coordinates(CIE) of the(SrBaSm)Si2O2N2:(Eu^3+Ce^3+) blue-green phosphors and the color conversion glass ceramics were studied in the sintering temperature range from 600℃ to 800℃. The luminous intensity and internal quantum yield(QY) of the blue-green phosphors and glass ceramics decreased with the sintering temperature increasing. When the sintering temperature increased beyond 750℃, the phosphors and the color conversion glass ceramics almost had no peak in photoluminescence(PL) and excitation(PLE) spectra. The results showed that the blue-green phosphors had poor thermal stability at higher temperature. The lattice structure of the phosphors was destroyed by the glass matrix and the Ce^3+ in the phosphors was oxidized to Ce^4+, which further caused a decrease in luminescent properties of the color conversion glass ceramics.

A more exact model of phycobilisomes has been designed with the rods composed of the hexamer disks and an abstract allophycocyanin (APC) core. Based on this model, the excitation energy transfer was simulated using the computer simulation technique. The simulation shows that the excitation energy is transferred from the outlayer disk to the core in a partly reversible way in phycobilisomes, and that the transfer rate from the last disk to the core is less than those between disks. The energy transfer between the two trimers in a hexamer is dominantly through the α84-chromophores (m), while that between the disks is through the β84-chromophores (f) that are also responsible for the transfer of energy into the core.

The mechanism of state transition in blue-green alga Synechocystis PCC 6803 was investigated by using modulated fluorescence. NaF, an inhibitor of phosphatase, did not inhibit state Ⅱ to state Ⅰ transition . Rotenone, a specific inhibitor of NAD(P)H ubiquinone reductase, stimulated transition from state Ⅱ to state I in dark. The results suggest that state transition in blue-green alga Synechocystis PCC 6803 is controlled by redox state of plastiquinone pool, but not by the phosphorylation of thylakoid membrane proteins.

CCC plasmid was isolated from an economically important blue-green alga- Spirulina platensis (1.7×106 dalton from the S6 strain and 1.2×106 dalton from the F, strain) using a rapid method based on ultrasonic disruption of algal cells and alkaline removal of chromosomal DNA. The difference in the molecular weight of the OOC DNAs from the two strains differing in form suggests that plasmid may be related with the differentiation of algal form. This modified method, which does not use any lysozyme, is a quick and effective method of plasmid isolation, especially for filamentous blue-green algae.
