摘要

Abstract

Solid-state phosphorescent materials with stimulus-responsive properties have been widely developed for diverse applications. However

the task of generating excited states with long lifetimes in aqueous solution remains challenging due to the ultrafast deactivation of the triplet excitons and the difficulty in regulating stimulation sites in an aqueous environment. Additionally

most existing materials are primarily responsive to limited stimuli

such as light

oxygen

or temperature. Here

we present a microscale rigid framework engineering strategy that can be used to modulate the phosphorescence properties of carbon nanodots (CNDs)

by brightening triplet excitons through ultrasound-enhanced rigidity in CNDs. Ultrasound-responsive phosphorescent CNDs with a lifetime of 1.25 seconds in an aqueous solution were achieved. The CNDs exhibit high sensitivity to surrounding ultrasound

showing a linear response to ultrasound exposure during the treatment period. The ultrasound-responsive phosphorescent CNDs demonstrate potential applications as sensing units in ultrasound radar detection and in vivo afterglow imaging.
