Study on optical properties of l-valine doped ADP crystal

摘要: Abstract Single crystal of l -valine doped ammonium dihydrogen phosphate has been grown by slow evaporation method at room temperature. The crystalline nature the was confirmed using powder X-ray diffraction technique. different functional groups were identified Fourier transform infrared analysis. UV–visible studies employed to examine high optical transparency and influential constants for tailoring materials suitability optoelectronics applications. cutoff wavelength title found be 280 nm with wide band gap 4.7 eV. dielectric measurements carried determine constant loss characterized thermogravimetric second harmonic generation efficiency determined classical Kurtz technique it is 1.92 times that potassium phosphate. as third order nonlinear material employing Z -scan He–Ne laser operating 632.8 nm.
