英文摘要Polarized infrared reflectivity measurements between 300 and 10 K have been carried out on charge density waves (CDW) conductor blue bronze Tl0.3MoO3. Three important features are observed: (i) A bump at 1155 cm(-1) in the reflectivity spectra of Tl0.3MoO3 at 300 K is a precursor of the Peierls gap due to optical excitations across a pseudogap, and this kind of Peierls-like gap opens gradually with decreasing temperature from 180 to 160 K. (ii) The three sharp modes as "triplet" of infrared reflectivity between 800 and 1000 cm(-1) of Tl0.3MoO3 along [102] axis show red shift compared to K0.3MoO3 and Rb0.3MoO3, which is assigned to the increase of the distance of Mo-O bond with the substitution of thallium ions. (iii) Two peaks at about 514 and 644cm(-1) in the far-infrared reflectivity spectra of Ti0.3MoO3 along [102] direction are suggested to be the electronic transitions from the valence band to the midgap state and from occupied midgap state to the conduction band, respectively.
