Abstract
This paper demonstrates that laser desorption/ionization time-of-flight mass spectrometry (LDI-TOF-MS) can be utilized to analyze the relative atomic composition and photothermal conversion properties of Au– Ag alloy nanoplates synthesized by galvanic replacement reactions. Using Au– Ag alloy nanoplates with various shapes, it is found that the porous structures of the nanoplates affect their photothermal conversion efficiency more than their laser energy absorption capacity does. Based on these findings, the optimized Au– Ag alloy nanoplates can be applied to LDI-TOF-MS of small molecules.
