The preparation and luminescent properties of AlPO4 mesoporous glass impregnated with Tb3+ ions
Source abstract
Abstract
Abstract Intense room-temperature terbium photoluminescence, with well-resolved optical bands corresponding to electron transitions 5 D 4 → 7 F j (j = 3–6) was observed from mesoporous AlPO 4 glass after immersion in solutions of terbium nitrates and subsequent heat treatment. The modification of Tb ions for the AlPO 4 network structure is revealed by XPS spectra. The PL mechanism of the formed nanocomposite is discussed through the effects of Tb concentration and excitation wavelength. Our results indicate that the mesoporous AlPO 4 glass is a suitable matrix to incorporate rare earth ions as the light emitting material.
