摘要: Here we demonstrate crystalline phase induced Raman enhancement on molybdenum carbide materials (beta-Mo2C and alpha-MoC). From all the studied target molecules (rhodamine 6G, crystal violet and methylene blue), the Raman enhancement on beta-Mo2C is 2-4 times higher than that on alpha-MoC. Spectroscopic and theoretical calculations reveal that beta-Mo2C has a lower electron work function and a higher density of states near the Fermi level than alpha-MoC, which promotes the charge transfer and photo induced charge transfer processes from probe molecules to the substrate.
