“…Nonlinear optical devices based on second harmonic generation, crystal oscillators and rescuators, and devices to central laser emission are some of these applications. It has also been identified as a strategic material with a global business potential (Selvasekarapandian et al 1999). TGA and DTA studies on STT (Rahimkutty et al 2001) have concluded that water molecules are locked up with different strengths in the crystal lattice.…”

Strontium tartrate trihydrate (STT) crystals have been grown in silica hydrogel. Various polarization mechanisms such as atomic polarization of lattice, orientational polarization of dipoles and space charge polarization in the grown crystals have been understood using results of the measurements of dielectric constant (ε ε′ ′) and dielectric loss (tan δ δ) as functions of frequency and temperature. Ion core type polarization is seen in the temperature range 75-180°C, and above 180°C, there is interfacial polarization for relatively lower frequency range. One observes dielectric dispersion at lower frequency presumably due to domain wall relaxation.

Calcium mixed strontium tartrate crystals were grown by controlled diffusion in silica gel at ambient temperature. Structural characterization of the grown crystals was carried out by single crystal and powder X-ray diffraction analysis. The functional groups present in the crystals were identified using Fourier transform infrared spectral analysis. The chemical composition of the sample was verified using EDAX spectrum. The nonlinear optical property of the grown crystal was confirmed by Kurtz-Perry powder technique. The UV-VIS-NIR transmission spectrum was recorded to study the optical transparency of the grown crystal. Mechanical strength of the grown crystals was analyzed by Vicker's microhardness test.

“…Tartrate single crystals find application in non-linear optical devices because of their optical second harmonic generation, optical transmission characteristics, fabrication of crystal oscillators and resonators and controlled laser emission [4][5][6][7][8][9]. Strontium tartrate exhibits pyroelectric and ferroelectric transitions [10], non-linear optical and spectral characteristics [11] and dielectric and optical properties [12].…”
