Hello everyone,

I’m currently analyzing XRD patterns and looking for the JCPDS (PDF) reference files for the following materials:

• Gold (Au) – JCPDS Card No. 04-0784
• Platinum (Pt) – JCPDS Card No. 04-0802
• Graphitic Carbon Nitride (g-C₃N₄) – JCPDS Card No. 87-1526

If anyone has the PDF cards or the data (especially the reference peak positions, d-spacings, or intensity patterns), I would greatly appreciate it. Open-access sources are welcome too!

Thank you so much in advance 🙏
