“…The Raman spectra of nominally pure TGS and CA crystals used to prepare TGS:CA crystals consist of a series of lines 10 cm −1 wide, located in the range of 50-3200 cm −1 . The spectra obtained are in good agreement with those known from the literature [10,[25][26][27][28]64,65]. Figure 5 shows a comparison of Raman spectra of nominally pure TGS used for the growth of TGS:CA single crystals from aqueous solution, and TGS crystal doped with croconic acid, TGS:CA (90:10).…”

“…Comparison of FTIR absorption spectra of TGS:CA (90:10) and pure TGS in the spectral range of 800-3500 cm −1 are presented in Figure 6a. Most of lines observed in the TGS:CA crystal correspond well to those in pure TGS [13,15,19,25,32,33]. Figure 6b shows absorption spectrum of TGS:CA for ν = 4000-4800 cm −1 .…”

“…Incorporation of doping atoms or molecules in TGS crystal lattice can be successfully used for achieving a "unipolar" ferroelectric state [7][8][9] in TGS, improving their nonlinear optical [10], pyroand piezoelectric properties [11][12][13], etc. At present in the literature, there is information about TGS crystals doped with metal ions and nanoparticles [14][15][16], amino acids [9,[17][18][19][20][21][22], organic acids [23][24][25][26][27], inorganic acids and salts [13,[28][29][30][31][32][33][34]. Doping of TGS with various organic molecules with a dipole moment from 4 to 6 Debye shows that the greater the dipole moment of the impurity molecule, the higher the spontaneous polarization P s and the pyroelectric coefficient p of the doped crystals.…”

Triglycine sulfate (TGS) single crystals doped with croconic acid (CA) were grown by evaporation from aqueous solutions. X-ray diffraction analysis shows a slight reduction in unit cell volume in TGS:CA compared to pure TGS crystals. The polarized Raman and near-infrared absorption spectra show that the positions of most lines resulting from inter- and intramolecular vibrations are in good agreement with those in spectra of undoped TGS crystals. The inclusion of CA in TGS is confirmed by the presence of bands characteristic of CA in the infrared-Fourier transform spectra. The ultraviolet-visible absorption spectra of TGS:CA are characterized by the presence of additional absorption bands (compared to the spectra of pure TGS) located in the transparent region of pure TGS. In the photon energy region 1.6–3.6 eV, a strong “green” luminescence band is present in TGS:CA upon excitation at λ = 325 nm. The position of the emission band depends on the wavelength of the exciting light. Doping of TGS with CA causes pinning of domain walls, which is accompanied by a decrease in amplitude and frequency dispersion of the dielectric anomaly at the phase transition, a decrease in the switchable polarization and an increase in the coercive field of hysteresis loops.

Transient implantable piezoelectric materials are desirable for biosensing, drug delivery, tissue regeneration, and antimicrobial and tumor therapy. For use in the human body, they must show flexibility, biocompatibility, and biodegradability. These requirements are challenging for conventional inorganic piezoelectric oxides and piezoelectric polymers. We discovered high piezoelectricity in a molecular crystal HOCH 2 (CF 2 ) 3 CH 2 OH [2,2,3,3,4,4-hexafluoropentane-1,5-diol (HFPD)] with a large piezoelectric coefficient d 33 of ~138 picocoulombs per newton and piezoelectric voltage constant g 33 of ~2450 × 10 −3 volt-meters per newton under no poling conditions, which also exhibits good biocompatibility toward biological cells and desirable biodegradation and biosafety in physiological environments. HFPD can be composite with polyvinyl alcohol to form flexible piezoelectric films with a d 33 of 34.3 picocoulombs per newton. Our material demonstrates the ability for molecular crystals to have attractive piezoelectric properties and should be of interest for applications in transient implantable electromechanical devices.

“…Triglycine sulfate ((NH2CH2–COOH) 3 _H 2 SO 4 :TGS) is an interesting ferroelectric material which has been extensively studied for its application as room temperature IR detector. The crystal symmetry of TGS is monoclinic with the space group P21 in the ferroelectric phase and in the paraelectric phase the structure exhibits two mirror planes at y = 1/4 and 3/4 and the space group becomes P2 1 /m .…”

Triglycine sulfate crystal added with 0.5 mole% nickel sulfate of 15 mm diameter and 150 mm height has been grown from an aqueous solution using Sankaranarayanan–Ramamasamy (S‐R) method in [001] direction. The grown crystal was studied by various characterization techniques. Thermogravimetry analysis reveals that the NiSO4 added TGS crystal is more thermally stable than pure TGS crystal. The presence of nickel in the TGS‐NiSO4 crystal was confirmed by atomic absorption spectroscopic (AAS) technique and its concentration was found to be 284 ppm. The surface of the grown crystal was investigated using atomic force microscope (AFM). It revealed the surface defects of the doped TGS crystal.
