08 June 2025 0 2K Report

Hello, distinguished professors. I hope you can help me accurately answer my question. When I prepared the graphene quantum dots and when I shone ultraviolet rays, these beams or rays appeared, and I do not know the reason. Is there an explanation for this? I hope you can help me clarify, noting that the ultraviolet rays that I used were in the form of multiple LEDs
