摘要： Color conversion films with haze have aroused interest for use in surface light sources for display and lighting applications. Surface patterning or addition of light scattering particles to the color-conversion film induces haze and consequently, improves the photoluminescence (PL) extraction. Herein, a CdSe/CdZnS quantum dots (QDs)-embedded glass fiber reinforced siloxane hybrid (QD-GFRH) film with high haze value is demonstrated, originating from refractive index mismatch between glass fiber and methacrylate-phenyl functionalized siloxane matrix. The hazy QD-GFRH film shows a twofold improvement in PL extraction, as well as robust mechanical properties, such as low thermal expansion (13 × 10?6 K?1) and high deformation resistance (E = 11.8 GPa), compared to conventional polymers. Because QDs are chemically dispersed inside the film by covalent crosslinking with siloxane matrix, the QD-GFRH film exhibits long-term (30 days) thermal and chemical stability against heat and moisture conditions [85 °C/5% relative humidity (RH), and 85 °C/85% RH]. Furthermore, the yellow photoemissive QD-GFRH film, with a smooth surface and large scale (A4 size, 210 mm × 297 mm size), is applied as a color-conversion film on a blue light-emitting diode and it covers a large color gamut (107% relative to National Television System Committee).
