The diffuse reflectance and photoluminescence (PL) spectra of NdI(2), SmI(2), EuI(2), DyI(2), TmI(2) and YbI(2) were measured between 225 and 12 500 nm in order to determine their 4f(n) → 4f(n-1)5d(1) optical bandgaps. The results were compared with those obtained using an empirical model of the ele... View More
