摘要：

Colorless single crystals of bismuth silicon oxide (BSO) have been grown using a pressure-balanced hydrothermal technique. The absorption shoulder which causes the yellow coloration observed in conventional BSO was completely missing in the hydrothermal material. The 10 K absorption edge was found to be 3.45 eV for the hydrothermal samples. Because of the absence of a low-temperature photochromic response and the observation of only very weak TSC peaks, it appears that the hydrothermal crystals represent near-intrinsic BSO. When a crystal was pulled from a melt of hydrothermal material, the yellow coloration returned.
