Abstract
An electroluminescent lamp is presented, wherein at least one of the phosphor layer or the dielectric layer comprises a polyureasilazane polymer. The polyureasilazane may be added to the fluoropolymer resin of the phosphor layer or the dielectric layer, and/or may be used to coat the phosphor particles within the phosphor layer or the inorganic filler particles within the dielectric layer. Use of polyureasilazanes confers enhanced adhesion and environmental resistance.
