Abstract
Acoustoโoptical materials play an important role in acoustoโoptic devices as acoustoโoptic modulators. Lead(II) chloride is an acoustoโoptical material, having high figure of merit approximately ten times greater than that of lead molybdate, which is an efficient acoustoโoptical material. It also possesses high birefringence, low attenuation coefficient, wide transparency range and good mechanical properties. This paper discusses in detail, the growth of single crystals of lead(II) chloride in silica gel by the process of diffusion in a highly acidic medium. Needleโtype lead(II) chloride crystals have been obtained. The crystal system is confirmed to be orthorhombic by powder Xโray diffraction analysis. To study the optical transparency of the grown crystal, the transmission spectrum has been recorded in the range 190 โ 1100 nm. Thermal stability of the crystal is also studied. Results are discussed in detail. (ยฉ 2008 WILEYโVCH Verlag GmbH & Co. KGaA, Weinheim)
