Pulse-duration dependence of saturable and reverse saturable absorption in ZnCo2O4 microflowers
Pritam Khan, Rajesh Kumar Yadav, Anirban Mondal +2
We employed open-aperture Z-scan technique to unveil the third-order optical nonlinearity in ZnCo2O4 (ZCO) microflowers. Our results indicate that intersystem crossing (ISC) lifeti…
