Dense nanocrystalline glass ceramics of the Li 2 O–Al 2 O 3 –SiO 2 (LAS) system were obtained by spark plasma sintering (SPS) of powders prepared by sol–gel method. The low thermal expansion LAS glass ceramic was chosen as host matrix for erbiu

Low thermal expansion Li(2)O-Al(2)O(3)-SiO(2) (LAS) glass ceramic was examined as a host matrix for erbium ions. ZrO(2) was added to the glass since it serves as a nucleating agent and as a good environment for the luminescent ions. The study was car

We report the synthesis and the spectroscopic properties of a novel soluble thiophene-based copolymer carrying pendant fullerene moieties (donor–acceptor double-cable polymer). Photoinduced absorption (PIA) experiments on spin cast films reveal a p
