Triglycine Sulfat[(NH2CH2-COOH)3H2SO4]晶体具有良好的热释电性能。在大多数红外区域内，它表现出强大的吸收能力。在室温下，其热释电系数价值是最高的。它适合被用于制作高速宽带红外热释电探测器和摄像机，同时，这是用于制作二氧化碳（二氧化碳）激光（ 10.6μm ）和氰化氢激光（ 337μm ）的合适材料。

Deuterated Triglycine(DTGS) crystal has a Curie temperature which can be raised to 57-62℃ thus the temperature ranges of the devices made of it can also be raised. L-alanine doped deuterated triglycine sulfate(DATGS) crystal creates inherent bias field due to the doping, preventing the crystal from depolarization, and the pyroelectric property is greatly raised.

DATGSP and DATGSAs are phyophoric acid and arsenic acid doped DATGS(Lalanine doped deuterated triglycine sulfate) crystals respectively. The pyroelectric coefficient of these two crystals are evidently raised.
