Produced with tight size control and excellent purity, these GQDs exhibit lateral dimensions \u0026lt; 10 nm, a thickness range of 1–6 nm, and strong photoluminescence in aqueous systems. Their stable fluorescence and excellent water dispersibility make them ideal for bio-labeling, fluorescence materials, optoelectronic devices, and multifunctional composite systems.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003ch3\u003eAppearance:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eWhite to light-yellow powder\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eParticle Characteristics:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eThickness: 1–6 nm (AFM)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eLateral Size: \u0026lt;
