Research on hybrid inorganic‐organic materials has experienced an explosive growth since
the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild …

Over the past decades extensive research has been carried out to study the lasing
characteristics of random media. Some unexpected phenomena of random lasing action …

The advances in optoelectronics over the last three decades have been quite dramatic,
namely the mass manufacturing of low cost integrated circuits, revolutionizing the speed and …

Luminescent solar concentrators (LSCs) appear as an intriguing way to cope with the
limitation of the mismatch between the photovoltaic (PV) cells response and the solar …

We demonstrate random lasing action in flexible bacterial cellulose (BC) membrane
containing a laser-dye and either dielectric or metallic nanoparticles (NPs). The novel …

An upconversion random laser (RL) operating in the ultraviolet is reported for Nd^ 3+ doped
fluoroindate glass powder pumped at 575 nm. The RL is obtained by the resonant excitation …

Lasing from a planar waveguide with the blend of Polystyrene (PS): Poly-
methylmethacrylate (PMMA) doped with tris (8-hydroxyquinolinato) aluminum (Alq_3) and 4 …

A Rhodamine B-doped 3-glycidoxypropyltrimethoxysilane (GPTS)/tetraethyl orthosilicate
(TEOS)-derived organic/silica monolithic xerogel with excellent optical properties was …

The features of fluorescence emission in a dye-doped dense multiple scattered medium
under pulsed laser pum** are considered in terms of confined excitation in small zones …

This work reports the synthesis of novel sol–gel derived urea cross-linked tripodal siloxane-
based hybrids (classed as tri-ureasils) modified by the addition of phenyltriethoxysilane …
