摘要: As‐received and 60Co‐irradiated cultured quartz is characterized using low‐temperature near‐infrared Fourier spectroscopy, peaks associated with as‐grown hydroxide (OH) aluminum (Al‐OH) point‐defect centers are measured. Defect‐center distributions determined from scanning small crystal regions parallel or normal to the crystal‐growth axis. Large variations in point defects observed arising substitutional interstitial impurity concentrations along For initial radiation doses OH decreases uniformly across forms Al‐OH, but Al‐OH peak strength varies considerably different sections. This indicates possibility of radiation‐induced hydrogen diffusion over large distances compensate nonuniformities aluminum‐ion distribution. With increasing dose may stabilize a constant level some deplete other crystals, continues form ev...
