From: A green route to prepare fluorescent and absorbent nano-hybrid hydrogel for water detection
The structural model of hydrogel, inset shows the typical optical micrograph image of hydrogel of different swelling ratios respectively for 50 times(a), 100 times(b), 150 times(c). Excitation−emission maps of hydrogel absorbed the water (d) 50 times, (e) 100 times, (f) 150times and the corresponding contour maps.
