The resonance scattering (RS), fluorescence, adsorption spectra and mean diameters of Te(Ⅳ)- I~--RhB liquid phase nanoparticles under different conditions were studied. The results show that fluorescence quenching and enhancement of RS intensity were obviously observed due to the formation of [(RhB)_4(TeI_8)]_n nanoparticles. Their average diameters increased with the concentration of Te (Ⅳ) in the range of 0—20 μg/L. The maximum resonance scattering peak was at 623 nm. The cube root of I_(623 nm/623 nm) was proportional to the average diameter of the nanoparticles. The nanoparticles were characterized by ICP-AES, EA. The results indicate that the molecular formula was (RhB)_4(TeI_8).
