In this paper, the delayed luminescence of ginseng produced from two different areas was determined with the self built
bioluminescence detecting system. And the attenuation curve of bioluminescence of the experimental samples were
studied, before and after the samples extracted by 58% alcohol. We primarily gave out the parameters describing
emitting characteristic. Using the method of optic induced bioluminescence, we also determined the weak luminescence
emitting from the ginseng tuber, and find the intensity and decay time having obvious difference from skin and core,
with these data we can distinguish the producing area and feature of the ginseng. In the experiment, the light-induce
luminescence of the sample was menstruated, which has been infused by water and 58% alcohol; the difference between
two kinds of samples which were infused and not infused has been delivered. In order to investigate the effect of
excitation-light spectrum component to delayed luminescence of ginseng, a light filter witch allow a wavelength scope of
225nm~420nm pass through was installed between the light source and sample, keeping other work condition unchanged,
the bioluminescence was also determined. For investigating the effect of extracting to emitting, the absorption spectrum
of above samples ware studied, and the time-sequence of absorption spectrum was obtained. Based on the data obtained
from our experiment, we analyzed the radiation mechanism of ginseng slice and tuber.
In this paper, the influences of cyanine dye on the photoelectron decay of silver chloride micro-crystal have been studied
with Microwave absorption and dielectric spectrum detection technology. The free photoelectron decay of silver halide
sensitized becomes faster than that of pure silver halide, and the FDT are 86ns and 109ns for silver chloride
sensitized(5.0ml/40g AgCl emulsion) and unsensitized, respectively. The absorption peak of the dye is at about 550nm,
having about 50 nm red shift compared with that in methanol. This indicates that J- aggregate is formed on micro-crystal
surface, moreover the peak of dye J-aggregate becomes sharper, the width of absorption peak narrower with the
increasing of the concentration of dye. Dye J-aggregate increases the concentration of deep electronic trap in the surface
of silver halide micro-crystals.
