The impact of glycine on the synthesis of colloidal In2O3 nanocrystals and their optical characteristics

Using the sol-gel method, high-quality colloidal In 2 O 3 nanocrystals were synthesized. Glycine was used as a surfactant to control the optical properties of the resulting sample. Various characterization techniques were utilized to examine the structural and optical properties of colloidal In 2 O 3 nanocrystals. Studies have shown that glycine functionalizes the surface of colloidal In 2 O 3 nanoparticles, causing only a slight alteration in their optical band gap. It has been observed that the emission intensity of colloidal In 2 O 3 increases as a result of glycine surface modification. The colloidal In 2 O 3 nanocrystals emitted a bluish-white light. The use of glycine appears to have facilitated the formation of nitrogen dopants in colloidal indium oxide nanoparticles. The experimental results confirm the successful production of highly stable colloidal nanocrystals with strong white emissions, suggesting their potential for photonic applications, such as in light-emitting diodes.
