的蒽的三维荧光光谱及浓度比为1:1的蒽-芴、蒽-萘、蒽-菲、蒽-苊、蒽-荧蒽的三维荧光光谱进行了测定,并通过分析不同压力下蒽的荧光峰位置和峰强度的变化来探讨压力对荧光光谱的影响。结果显示,随着压力升高,蒽的荧光峰并未发生漂移,但是荧光强度发生了显著变化。峰位置为250/382 nm的荧光峰在60 MPa时荧光强度达到最大值,相较于常压下,荧光强度增加了13.6%。其他多环芳烃的加入会改变蒽的高压荧光特性,当蒽中加入了萘,峰位置为250/382 nm的荧光峰强度在10 MPa时达到最大值,相较于常压下,荧光强度增加了9.35%。
The effects of hydrostatic pressure on the three-dimensional fluorescence spectra (3DFS) of pure anthracene (10

) and its mixtures (anthracene-fluorene
anthracene-naphthalene
anthracene-phenanthrene
anthracene-acenaphthene
anthracene-fluoranthrene
and the concentration ratios are 1:1) were investigated in a pressure range of from 0.1 MPa to 60 MPa at room temperature. The variation of 3DFS under high pressure was revealed by analyzing the positions and intensities of fluorescence peaks with the increase of hydrostatic pressure. It is found that the fluorescence peak shifts are not detected
however
the changes of fluorescence intensities are observed (
e.g
. anthracene
the fluorescence intensity of peak of 250/382 nm reached its maximum when the pressure was increased to 60 MPa
and the intensity increases 13.6% compared with that of 0.1 MPa). Otherwise
the high pressure fluorescence properties of anthracene are changed profoundly with the addition of other PAHs (
e.g
. anthracene) is mingled with naphthalene
the fluorescence intensity of peak of 250/382 nm reaches its maximum when the pressure increases to 10 MPa
and the intensity increases 9.35% compared with that of 0.1 MPa.
