20.500.12556/RUL-174754 Exploring the interplay between formation mechanisms and luminescence of lignin carbon quantum dots from spruce biomass This study investigates the intricate relationship between the formation mechanisms and luminescent properties of lignin-derived carbon quantum dots (LG CQDs) synthesized from spruce biomass by hydrothermal treatment. A comprehensive understanding of LG CQDs structure and its photoluminescence requires insights into the native architecture of lignin and the distribution of its acidolysis-derived fragments. Research showed how these lignin-derived units interact with dopant molecules in three different approaches during synthesis, contributing to core and surface structures that govern optical behavior. In our experiments, m-aminophenylboronic acid and varying amounts of HCl were employed as dopants to further tune the structural and luminescent features of the CQDs. The presence of functional groups such as amino, hydroxyl, and boronic acid groups was found to be crucial for enhancing the luminescent properties of the CQDs. Our findings reveal a clear correlation between structural features and luminescent properties, emphasizing the role of surface chemistry in tuning emission characteristics. These insights provide a foundation for the rational design of LG CQDs with tailored luminescent properties, advancing their potential applications in sustainable optoelectronics, sensing, and bioimaging. spruce biomass lignin carbon quantum dots luminescence biomasa smreke lignin ogljikove kvantne pike luminescenca true false true Angleški jezik Slovenski jezik Članek v reviji 2025-10-09 13:46:05 2025-10-09 13:46:06 2026-06-17 04:10:52 0000-00-00 00:00:00 2026 0 0 9 str. pt. 1, art. 113301 Vol. 246 Mar. 2026 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 620.3:665.947.4 0143-7208 10.1016/j.dyepig.2025.113301 252524291 1-s2.0-S0143720825006710-main.pdf 1-s2.0-S0143720825006710-main.pdf 1 FE89FF2C2F32E92F4F8738FC8B01F7FA 6f59398c9bb51abde875f987c111d2e79039da35548803cc86be2af3e197f98e bb44c56c-6974-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=235735 https://www.sciencedirect.com/science/article/pii/S0143720825006710 1 4e323171-a505-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=219637 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
