A large number of tungstate (AWO4) and molybdate (AMoO4), where 'A'
stands for large size divalent ions like Ca, Pb or Ba are naturally
occurring crystals. Their scheelite structure is characterized by
tetrahedrally coordinated (WO4)2-/(MoO4)2- group positioned at four
corners of a unit cell and the divalent A2- located at bcc is
octahedrally coordinated with oxygen ions. Though scheelites have
been investigated for over 50 years, issues related to their
luminescent emission still remained unresolved. In this thesis
single crystal growth experiments on lead molybdate PbMoO4 (PMO),
barium tungstate BaWO4 (BWO), and sodium bismuth double tungstate
NaBi(WO4)2 (NBW) have been carried out using the Czochralski (CZ)
technique. Structural, electronic and optical properties of these
three crystals, all having the same crystalline structure were
investigated experimentally as well as theoretically. Specific
aspects as (a) material synthesis (b) crystal growth (c)
transmission and coloration (d) photoluminescence and (e)
electronic structure have been discussed in detail.
