Triglycine Sulfate crystals have technological importance for
room-temperature infrared detectors, earth exploration, radiation monitoring
and astronomical telescopes. TGS is the best material applied 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 the wavelength
range from ultraviolet to far infrared and do not require cryogen cooling
for operation. The use of deuterated DTGS crystals allows to extend temperature
range of sensing due to their higher Curie temperature.
L-α-Alanine Doped TGS
Doping with La -Alanine
significantly improves and orders domain structure and turns the material
to a hard ferroelectric.
