摘要

紫外-可见光谱表征表明，fe3o4 @CQD纳米复合材料在294 nm、325 nm、341 nm和362 nm波长处有四个吸光度峰。CQD的物理性质在可见光下呈透明色，而在紫外线下呈绿松石色。XRD测试结果显示，在hkl(002)平面上，CQD峰位于24.3⁰。fe3o4 @CQD纳米复合材料的晶粒尺寸为27.2 nm。

Sintesis dan Karakterisasi Sifat Optik Nanokomposit Fe3O4@CQD (Carbon Quantum Dots)

UV-VIS characterization, Fe 3 O 4 @CQD nanocomposite has four absorbance peaks at wavelengths of 294 nm, 325 nm, 341 nm, and 362 nm. The physical properties of CQD show a transparent color under visible light, while a turquoise color when exposed to UV light. The XRD test results showed a CQD peak at 24.3⁰ with the hkl (002) plane. The crystal size of the Fe 3 O 4 @CQD nanocomposite is 27.2 nm.
