A thin-film phosphor layer can be formed by an improved deposition method involving: (1) forming a phosphor powder layer that is substantially uniformly-deposited on a substrate surface; and (2) forming a polymer binder layer to fill gaps among loosely packed phosphor particles, thereby forming a substantially continuous layer of thin film.

A barrier film including a substrate; a base polymer layer adjacent to the substrate; an oxide layer adjacent to the base polymer layer; a adhesion-modifying layer adjacent to the oxide layer; and a top coat polymer layer adjacent to the adhesion-modifying layer. An optional inorganic layer can be applied over the top coat polymer layer. The inclusion of a adhesion-modifying layer provides for enhanced resistance to moisture and improved peel strength adhesion of the top coat polymer layer to the underlying barrier stack layers.

A compact electroluminescent laminar element includes a flexible electroluminescent lamp and an electronic module which is connected in the same layer as the lower electrode to the lamp and includes at least an electronic control component, an electronic component for activating the lamp, and a battery, where the lamp and the electronic module are housed together in an encapsulating substrate consisting of a textile or plastic material, forming a closed and compact element that can be water-impermeable. The activation component is a push-button, a temperature sensor, or a movement sensor. It also comprises a reflective layer.

Provided are modified hybrid sol-gel precursor solutions and coatings formed from such solutions. A modified hybrid sol-gel precursor solution includes an inorganic precursor, cross-linkable inorganic-organic precursor, cross-linkable organic precursor, protic solvent, and aprotic solvent. The inorganic precursor may include a metal or metalloid and two or more hydrolysable groups. The cross-linkable inorganic-organic precursor may include a metal, hydrolysable group, and organic molecule. The cross-linkable organic precursor has another organic molecule with two or more second cross-linking groups. A combination of protic and aprotic solvents in the same solution may be used to control properties of the solutions, thermodynamics, and other processing aspects. The solution may also include nanoparticles. The nanoparticles may include functionalized surface to form covalent bonds with one or more precursors of the solution, such as a plasma treated surface. The nanoparticles may be sized to fit into the sol-gel network without substantially disturbing this network.
