In this paper, the intermediate field energy matrices of the double-valuedgroup for d3 configuration are derived. The relationship among the crystal structureparameters, the ZFS parameter D and the splitting △E(2E) of the 2E state inCr3+:A12O3 laser crystal are established. On the basis of the hypothesis of thecrystal lattice distortion, the ZFS parameter D, Zeeman g factor, optical finespectra, and the splitting △E(2E) of the 2E state are calculated, the obtainedresults are in good agreement with experiment data reported in the literatures. Theresults show quantitatively that the six O2- ligand moves towards the central Cr3+ion by O.OO325 nm, meanwhile, the front three O2- of the Cr3+ rotate O.286° toward[111] axis while the back three O2- rotate 1.118° toward it..

[in Chinese], [in Chinese], [in Chinese], [in Chinese], [in Chinese], and [in Chinese]
The effect of energy transfer is an important phenomenon in luminescence material. Energy transfer between 5, 6, 11, 12 -tetraphenyltetracene(Rubrene) and N, N'-bis-(1-naphhyl)-N, N'-diphenyl-l,l'-biphenyl-4,4'-diamine(NPB) has been studied in organic thin film by time-resolved spectra and emission spec
The effect of energy transfer is an important phenomenon in luminescence material. Energy transfer between 5, 6, 11, 12 -tetraphenyltetracene(Rubrene) and N, N'-bis-(1-naphhyl)-N, N'-diphenyl-l,l'-biphenyl-4,4'-diamine(NPB) has been studied in organic thin film by time-resolved spectra and emission spectra. The dynamics equations were discussed to explain these process, andthe solutions obtained can be compared to the computer simulation with the experimental results. White light emission can be produced by adjusting the concentration of Rubrene in photoluminescence. However, with devices of structureITO/CuPc/NPB:Rubrene/TPBi/Alq/Mg:Ag with a blocking layer, the white lightemission can not be obtained by adjusting the concentration of Rubrene in electroluminescence. The mechanism of energy transfer has some difference in electricfield..

Using an ultra-weak bioluminescent image detecting system, the delayedluminescent (DL) images of Excoecaria cochinchinnensis leaves and some other plantspecies are detected. The results show that the DL can offer the important information of photosynthesis, cell division and energy transformation of plant species.Chlorophyll plays an important role in the plant DL. However cell division alsohas some influence on DL. The measured photon count rate after light illuminationcan be approximated by a hyperbolic decay law, which supports coherence theory.Whereas, two-exponential law also accords with measured data, which shows thatDL perhaps comes from two photosystems in plant cells and each of them gives achaotic luminescence after induced by light..

Both simulated output power and spectral shape of SFS are shown to be in good agreement with the experimental results for the cases of SPB/SPF configurations. The theoretical analysis of SFS in double-pass backward configuration (DPB) are presented for the first time. It is shown that with certain reflectivity reflector, DPB SFS can provide not only higher pump efficiency but also larger spectral width than other configuration SFSs under stable operation conditions..

The focused-beam thermal blooming effect in the focusing range is studied experimentally. For steady thermal blooming, the variation of the relative radius of the focusing spot vs the distortion nmnber Nd and the variation of the focusing spot intensity integration over the Arry size vs the ratio of incident power to critical power are obtained. It indicates that the blooming in focusing range has serious influence on the beacon intensity distribution at the receiving pupil..
