FTIR搜索不支持對該樣品進行可靠的特定材料鑑定。雖然最近的譜庫條目是氧(-2)陰離子; 釔(+3)陽離子,但所有列出的譜庫相似度均為0.000,且無直接參考文獻或相關文獻確認。觀察到的光譜更保守地描述為一種含氧材料,顯示出強羥基或吸附水貢獻,並可能具有低波數無機或表面相關特徵
建議的下一步: Recollect the FTIR spectrum after improved background subtraction and control of atmospheric H2O/CO2 to test whether the 2306, 2355, 3435, and 1650 cm-1 bands decrease. Dry or heat the sample gently under vacuum or dry gas, then remeasure to determine whether the hydroxyl/water bands are due to adsorbed moisture or structural O-H groups. Obtain a broader and cleaner fingerprint-region spectrum below 1000 cm-1, since inorganic oxide and lattice assignments often depend on that region. If yttrium oxide or another metal oxide is suspected from sample context, confirm with elemental methods such as XRF, EDS, or XPS rather than relying on this FTIR search alone.
