摘要: This study compared Sb2Se3 material in the form of commercial polycrystalline bulk, sputtered thin film, and homemade using laser desorption ionization (LDI) time flight mass spectrometry with quadrupole ion trap spectrometry. It also analyzed stoichiometry SbmSen clusters formed. The results showed that bulk was more stable to film; its spectra expected cluster formation. use materials for surface-assisted LDI (SALDI), i.e., graphene, graphene oxide, C60, significantly increased intensity. In total, 19 were observed. Six novel, high-mass clusters-Sb4Se4+, Sb5Se3-6+, Sb7Se4+-were observed first when paraffin as a protective agent.
