摘要:
本文提出和初步研究了声致荧光方法,测出了三种luminol-氢氧化物水溶液的声致荧光光谱,并对比了它们的光致荧光光谱。结果表明,这类物质的荧光可以由声波激发获得,而且声激发和光激发的荧光波长都在luminol水溶液的光致荧光的发射波长370—750um之间,属于可见光和近紫外光;相对于光致荧光而言,声激发的这三种溶液的最大荧光峰呈现大致10—20um的红移。
Abstract:
This paper suggested and preliminary studied the sonofluorescent method. The sonofluorescence spectra of three luminol-hydroxide aqueous solutions have been detected and compared with their photofluorescence spectra. The results demonstrated that the fluorescence of the substances can be obtained by sonoexcitation and the fluorescence emission wavelengths,whether the sonoexcitation or the photoexcitation is adopted, are almost in the range of 370-750 um, the emission wavelengths of photofluorescence of luminol aqueous solution, and belong in the visible and near ultraviolet region. Also it seems that, with respect to the photofluorescence of the luminol-hydroxide aqueous solutions, the red shift of the maximum fluorescence peak of the solutions appeared in the sonoexcitation.
