Confined-domain crosslink-enhanced emission effect in carbonized polymer dots
Light: Science & Applications, 2022 Confined-domain crosslink-enhanced emission effect was first studied to reveal the photoluminescence mechanism of carbonized polymer dots (CPDs). A general strategy was exploited to synthesize CPDs exhibiting tunable photoluminescence properties.
