The optical absorption properties of lithium transition-metal phosphates (LiTMPO4, TM = Mn, Fe, Co, Ni) with nanoscale particle sizes (300–500 nm in diameter) have been measured. The measured edges have been compared with band gaps determined from their corresponding electronic band structure calcul...
