Photoluminescent organosilane-functionalized carbon dots as temperature probes

Organosilane-functionalized carbon dots (SiC-dots) were prepared by a simple one-pot hydrothermal approach. The photoluminescence (PL) properties of the SiC-dots revealed a reversible response toward the temperature (293–343 K). Through Si–O–Si bonding, temperature-sensitive PL SiC-dot films could be easily fabricated on glass substrates.
