Single Excited Dual Band Luminescent Hybrid Carbon Dots-Terbium Chelate Nanothermometer

The report introduces hybrid polyelectrolyte-stabilized colloids combining blue and green-emitting building blocks, which are citrate carbon dots (CDs) and [TbL]<sup>+</sup> chelate complexes with 1,3-diketonate derivatives of calix[4]arene. The joint incorporation of green and blue-emit...
