Abstract
Lead tungstate PbWO4 single crystals were grown from sodium metasilicate ge l and water solutions of lead acetate and sodium tungstate as the reagents. Crystals grown were several micrometer in size and by X-ray diffraction me asurements it was determined that they are only of the scheelite structure. No evidence of lead tungstate low temperature modification - raspite - was found. The emission properties of crystals were measured over the temperat ure interval 80 to 300 K and it was found that they are similar to those in PbWO4 crystals grown by the Czochralski method.
