| 摘要 |
<p>The invention relates to a photoactive structure (100) intended to receive light issued from a light source (200) and to emit light into a medium (300) of refractive index n0. The structure (100) comprises a substrate (110) of refractive index n1, the substrate (110) having at least one longitudinal first face (111) and a lateral side (113), and a photoactive layer (150) intended to react to the light emitted by the source by emitting light. The photoactive layer (150) has a refractive index n2. The layer extends along the first face of the substrate (111), and the substrate comprises a receiving surface portion (115) intended to receive light issued from the light source in a direction substantially perpendicular to the surface portion (115), the surface portion (115) extending so as to make an acute angleαwith the first face (111) respecting sin-1(n0/n1) <α< sin-1(n2/n1). The invention also relates to a process for manufacturing such a structure (100) and to an illuminating system.</p> |
