To green synthesis of highly yield photoluminescence carbon nanofibers/carbon quantum dots by pine fruit the ball milling assisted hydrothermal method was served. Different analysis such as XRD, EDS, elemental mapping and FT-IR analysis were used to study the product structure. The optical properties of the synthesized carbon nanomaterials were investigated by UV-Vis and PL analysis. Also, the effects of hydrothermal time and temperature on the PL intensity were studied. To study the product size and morphology SEM and TEM analysis were served. Also, the nu
