摘要：

This paper discusses the growth and properties of triglycine sulfate (TGS) crystals doped with urea. It was found that the normalized growth yield and pyroelectric and dielectric constants could be increased significantly by urea additions. TGS crystals doped with 5 and 10 wt% urea exhibited up to five times higher material figures of merit for infrared pyroelectric detectors compared with undoped TGS crystals. The Vickers hardness of doped crystals increased with urea content to about three times the undoped value in the [010] direction at 10 wt% urea. No significant increase in the hardness was found, however, in the [001] direction. Incorporation of urea in TGS crystals has been qualitatively estimated by Fourier transform infrared (FTIR) data.
