Plasmonic Observation of High-Density Nanoclustering in Low-Temperature H₂O.

ABSTRACT: There has been considerable scientific interest in comprehending the behavior and phase transitions of H₂O at the nanoscale in low temperatures. Herein, a highly sensitive and nondestructive surface plasmonic detection system operated at low temperatures to investigate the real-time nanoscale variation in H₂O density from a rapidly cooled thin ice layer formed at 77 K is employed. The nanoslit device exhibits a distinct plasmonic response at 180-250 K, correlated to an increase in the local density of H₂O at the nanometer scale. Along with theoretical analyses, it is revealed that high-density H₂O clusters form by vigorous aggregation of H₂O molecules within the interphase liquid region between polymorphic ice crystals.
