RESUMO

We prepared large single crystals of triglycine sulphate (TGS) using method of crystal growth from aqueous solution. Results obtained by the characterization of single crystals showed a high optical and structural quality, basic properties for the future development of infrared radiation detectores. Voltage responsivity, time and espectral responses of a detector prototype built with single crystals are presented. General considerations about crystal growth theory are presented with bibliographical review of principal result on dependence of the linear growth rate with relative supersaturation respecting three crystallographical directions. An approach on growth rate is realized with one of the experiments, showing one of the mechanisms acting in the growing from solution. Due to DFCM (Departamento de Física e Ciência dos Materiais) and some research groups in country interests another single crystals were growed, potassium dihydrogen phosphate (KDP) and toped TGS.
