ADTGS crystal structure ATGS, ADTGS Triglycine Sulfate doped with Alpha-alanine

Water-soluble Triglycine Sulfate crystals have technological importance for room-temperature IR detectors, earth exploration, radiation monitoring and astronomical telescopes. TGS is the best material used as a sensitive element in pyroelectric sensors due to its high pyroelectric coefficient, reasonably low dielectric constant, and the best quality factor. Pyroelectric sensors based on TGS are uniformly sensitive to radiation in wavelength range from UV to far IR and do need in cryogen cooling for operation.
Using of deuterated DTGS crystals allows to extend the temperature range of sensing due to their higher Curie temperature.
Doping with Alpha-alanine significantly improves and regulates domain structure and also transforms material to ferroelectric
