Cu2O NP and CuO NP were synthesized using glucose as reducing agent and no UV visible peak was found. The XRD confirmed the characteristic peaks of these NP.
UV visible spectrophotometry is a preliminary investigation to confirm the formation of NPs. However, if there are no peaks at all, it could be that the reduction process was not complete or the reducing agent was unable to reduce the Ag ion. I advise you vary the conditions of the reaction and/or the method of synthesis. I hope this helps.
You can also take in account not peaks in the UV-Vis analysis, but broad absorption through the spectrum. If there is a slight absorption on the visible region, it means that you have another energy levels of your material that have an absorption at several energy values.
How you did the analysis? Have you dispersed Cu Oxide NP in aqueous solution? It can have also a matrix effect of your solution prepared for UV-analysis.
Gustavo Henrique de Magalhães Gomes we suspend prepared metal nanoparticles in distilled water and take spectrum scan of the prepared suspension. The absorption spectrum gives straight line that is above at some height on the reference line. The spectrum is not zero but peak was not present.
Kousar Perveen it would be great if you share your spectrum.
