However, the mechanisms underlying their luminescence and regulation still require further exploration. Herein, blue, green, and orange CDs with different quantum yields were successfully prepared, by changing the thermal degradation behavior of the waste wheat bran/<em>o</em>-phenylenediamine <em>via</em> adjusting the pH of the acidic hydrothermal conditions. The structure–photoluminescence property relationship of the prepared multi-colored CDs was thoroughly analyzed and discussed, aiming to provide new insights into the luminescence red-shift mechanisms of CDs. It was found that the larger sp<small>²</small> domains, higher graphitization of carbon cores, increased graphitic nitrogen, and elevated levels of C<img>O functional groups contribute to the CDs' lower band gap, resulting in a red-shift of the emission fluorescence. Among them, the elevated levels of C<img>O functional groups are normally neglected for their contribution in the red-shift of CDs.

Consequently, these materials are employed in a wide range of applications, including lithium-ion batteries (LiBs). Interestingly, a variety of thin film materials can be deposited onto polymer substrates using the atomic layer deposition (ALD) technique. This is because the surface of many polymers has abundant reactive sites that are essential for the initial growth of ALD, such as functional hydroxyl –OH groups and –C<img>O polar groups, aiding the smooth growth of ALD materials. Moreover, the diffusion growth mechanism, which is initiated by the nucleation and infiltration of precursors, can enable the initial growth of ALD materials even if the polymers lack these reactive polar groups. As polymers are composed of several chains, they have microporous characteristics, forming voids between the polymer chains. Because of these characteristics, polymers are considered ideal material substrates for investigating the promising future of the widely used ALD technique.
