摘要

Potassium iodide doped L-threonine (LTPI) single crystal with improved second harmonic generation efficiency, thermal stability and optical transmission was grown by low temperature solution growth method from aqueous solution. The grown crystal has 1.22 times second harmonic generation efficiency compared to the standard potassium dihydrogen phosphate. LTPI has a high optical transparency over a wide spectral range 245-1083 nm and lower cut-off at around 219 nm. LTPI crystallizes in the orthorhombic crystal structure with space group P2_12_12_1. It is thermally stable up to 238°C. In this paper, the photoluminescence study, FT-IR spectroscopic study and elemental analysis have been presented.
