Perspective laser infrared optics material cesium iodide

Properties of cesium iodide prepared by different purification methods

“…To purify samples from the abovementioned absorbent inclusions in samples CsI-B above we have carried out the processing of the melt under vacuum in the presence of absorbent followed by the melt ÿltration (Antoniv et al, 1995). The resulting as-grown CsI-C crystal was visually of good quality, transparent and free from any inclusions.…”

“…." CsI crystals (Antoniv and Garapyn, 1997;Antoniv et al, 1995). The carbon absorbent of an enhanced strength is based on spherical granules of activated carbon with well-controlled transitional porosity.…”

“…Those methods of cesium iodide single crystal growth that achieved low amounts of oxygen-related impurities have also been presented (Antoniv and Garapyn, 1997;Antoniv et al, 1995). However, the e ect of raw material puriÿcation using di erent preparation methods has not been examined for cesium iodide yet.…”

“…Several techniques have been successfully used in our laboratory for the puriÿcation and preparation of a number of alkali halide crystals, particularly of CsI (Antoniv et al, 1995). Those methods of cesium iodide single crystal growth that achieved low amounts of oxygen-related impurities have also been presented (Antoniv and Garapyn, 1997;Antoniv et al, 1995).…”
