Carbon dots (CDs) offer broad structural and chemical tunability, yet their structure\u2013state\u2010device relationships remain poorly resolved.

Synthesis routes are treated as reaction environments that control these coupled descriptors rather than as direct predictors of optical gaps. Device architectures are compared according to the role of CDs as UV absorbers, interface modifiers, or spectral converters in Si, metal\u2010oxide, polymer, graphene, and carbon\u2010nanotube systems. Across these architectures, the central design challenge is to preserve localized UV\u2010selective states while enabling efficient charge separation and long\u2010range transport. Progress requires structure\u2010resolved synthesis datasets, quantitative interface verification, standardized stability testing, and function\u2010separated architectures that decouple UV absorption
