Optical absorption in SrC4H4O6· 3H2O crystals
SK Arora, V Patel, A Kothari, B Chudasama - Materials Science and …, 2004 - Elsevier
Study of optical absorption in the gel-grown strontium tartrate trihydrate (STT) single crystals
measured in UV–vis range at room temperature reveals transitions involving absorption and
emission of phonons. Based on the theory of interband optical absorptions, the electronic
transition near the fundamental absorption edge is analysed. Some feeble disorder in the
crystal is conceived to be present. The analysis carried out hereunder leads to estimation of
energy of the lattice phonons involved.
