The L-asparagine potassium dihydrogen phosphate crystal was successfully grown and characterized, showing good optical transparency and mechanical strength. The crystal's high second harmonic generation efficiency makes it a promising material for non-linear optical applications.
研究不足
The study is limited to the characterization of L-asparagine potassium dihydrogen phosphate crystals grown by slow evaporation technique. Potential areas for optimization include exploring other growth techniques and further enhancing the crystal's non-linear optical properties.
1：Experimental Design and Method Selection:
The crystal was grown using slow evaporation technique with deionized water as a solvent.
2：Sample Selection and Data Sources:
High pure L-asparagine potassium dihydrogen phosphate salt (E-Merck) was used.
3：List of Experimental Equipment and Materials:
Powder X-ray diffraction analysis, FT-IR analysis, Perkin-Elmer 783 spectrometer, Perkin-Elmer Lambda UV-visible-near infrared spectrometer, vickers micro hardness tester.
4：Experimental Procedures and Operational Workflow:
