研究目的
Designing a better nonlinear optical (NLO) material with a high laser damage threshold (LDT) and ideal second harmonic generation (SHG) response.
研究成果
Rb10Zn4Sn4S17 exhibits a more outstanding LDT effect (5 times that of AGS) and a wider experimental band gap (3.59 eV) compared to Sr3MnSn2S8. It also has an ideal SHG coefficient approximately 0.7 times that of AgGaS2, making it a promising candidate material in the IR region.
