Diamine compounds are widely used as surface modifiers in the functionalization of carbon quantum dots, yet effects different diamines on properties dots remain unclear. In this study, (P-CDs) were synthesized from peanut shell powder via a simple one-step microwave-assisted hydrothermal method. The these was modified through co-heating with ethylenediamine (EDA), o-phenylenediamine (OPD), m-phenylenediamine (MPD), and p-phenylenediamine (PPD). morphology optical P-CDs systematically analyzed. diamine-modified exhibited varying sizes similar crystal structures, significantly enhanced fluorescence yields, reaching 35.2% for EDA-CDs. EDA-CDs OPD-CDs demonstrated excitation-dependent emission behavior, while MPD-CDs PPD-CDs did not. Based EDA-CDs, probe high sensitivity Fe3+ developed, showing good linear response within concentration range 20–100 μM detection limit 2.768 μM. Additionally, ion recovery rate 100.85% both deionized tap water, indicating practical applicability.
