title: [Study on properties and resonance rayleigh scattering spectra of nanometer selenium(0) particles in liquid phase].
abstract: In the HCl solution, selenium (IV) and excessive ascorbic acid (Vc) formed selenium(0), which homogeneously and steadily existed in liquid phase system. The Se(0) particles were aggregating spheres and their sizes were 26-243 nm from transmission electron microscope (TEM) and laser light scattering image. The nanometer Se(0) solution produced strongest resonance rayleigh scattering (RRS) at 470 nm. The intensity of RRS at 470 nm was linear with the concentration of Se(IV) in the range of 2.82 x 10(-9) -5.64 x 10(-6) g x mL(-1) (r = 0.997). Moreover, obvious Second-order scattering (SOS) and multiple frequence scattering (MFS) appeared at the same time.
