The neutral homoleptic Ln(III) complex Ln(Tp)(3) (Ln = Sm, Eu, Tb, Yb; Tp = hydrotris(pyrazol-1-yl)borate) were used as dopants for the preparation of novel photoluminescent poly(methyl methacrylate) glasses indicated as Ln(Tp)(3)@PMMA. The doped polymers containing samarium, europium and terbium derivatives showed emission associated to f-f transitions in the visible range upon excitation with UV light, while a NIR emission was obtained from Yb(Tp)(3)@PMMA. The maximum incident wavelength able to induce emissions from the Ln(Tp)(3)-doped polymers depends upon the choice of the lanthanide ion. No meaningful antenna-effect was instead observed using dysprosium as metal centre.
