摘要：

Optical absorption and photoconductivity spectra of nominally pure BSO are obtained and reexamined in terms of component bands recently found in photorefractive erasure. Three components, peaked at 2.86, 3.06, and 3.10 eV, are found in the optical absorption. The photoconductivity spectrum between 2.0 and 3.0 eV can be fitted to the two first bands by assuming a quantum efficiency ratio of β2/β1 = 0.65. These results give further support to the analysis of the photorefractive erasure spectrum reported in a previous paper, and improve the band parameters given there.
