Journal ArticleDOI

Erbium luminescence in porous silicon doped from spin‐on films

TL;DR: Erbium photoluminescence at room temperature and at 77 K has been observed from porous silicon doped with erbium from a spin-on silica gel film.
Journal ArticleDOI

Anisotropic Light Scattering in Nanoporous Materials: A Photon Density of States Effect

TL;DR: In this article, the authors consider light scattering in porous materials in the context of spectral, spatial, and angular redistribution of photon density of states in materials with pores whose size and spacing are of the order of light wavelength.
Journal ArticleDOI

Strongly enhanced Tb luminescence from titania xerogel solids mesoscopically confined in porous anodic alumina

TL;DR: In this article, the optical bands attributed to 5D3→7Fi (i=3,4,5), 5D4→7Fj (i = 3, 4,5,6) transitions of Tb3+, with a predominant band at 2.28 eV, were investigated between 6 and 300 K.
Journal ArticleDOI

Impurity-driven defect generation in porous anodic alumina

TL;DR: In this article, the morphologies of porous anodic alumina films are affected significantly by the presence of small amounts of copper impurity in the aluminium substrate, resulting in generation of defects during anodizing in phosphoric acid over a wide range of conditions.
