“…After 3 minutes of heating with a domestic microwave (700W), the white powder will be changed to yellow powder (solid-state CNPs) which is able to fluorescent under UV light. To perform the solvatochromic behavior, the solid-state CNPs were dissolved in solvent variation based on the index polarity, such us water, DMSO, DMF and formamide [4,7]. The result show that the different color (blue to light green) of the CNPs solution was achieved under UV light with an excitation wavelength of 365 nm.…”

Carbon nanoparticles (CNPs) have garnered significant attention among researchers due to their cost-effectiveness and tunable properties, rendering them applicable in a wide array of fields, including biomedicine, optoelectronics, catalysis, and sensing. The solvatochromic effect denotes the phenomenon of a compound exhibiting a color change or a shift in its photoluminescence spectrum. In this study, we investigated the solvatochromic behavior of CNPs doped Nitrogen synthesized through the solid-state route using citric acid and urea, dissolved in solvents with varying polarity indices. Significant differences in emission were analyzed using a photoluminescence (PL) spectrometer. The results exhibit the emission shifting towards longer wavelengths (red region) as the solvent’s polarity index increased. This study of solvatochromic behavior in CNPs holds substantial significance for further research into their application as sensors.
