The optical spectra of trivalent rare earth ions (R3+) doped into single crystal yttrium oxide (Y2O3) have received considerable attention over the last two decades. A survey of the literature reveals that there is still disagreement over the interpretation of the crystal-field splittings and subsequent wave functions of in both C2 and C3i sites (1–3). Several calculations have appeared in the past for the optical spectra of Nd3+(4f 3), Er3+(4f 11) and Tm3+(4f 12) in C2 sites of Y2O3 and for R3+ in other crystals with C2 sites (4–7). Even less information is available regarding crystal-field splitting calculations for R3+ in C3i sites (2,3,8).
