摘要：
Lead tungstate PbWO4 single crystals were grown from sodium metasilicate gel and water solutions of lead acetate and sodium tungstate as the reagents. Crystals grown were several micrometer in size and by X-ray diffraction measurements 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 temperature interval 80 to 300 K and it was found that they are similar to those in PbWO4 crystals grown by the Czochralski method.
