摘要： An electro-luminescent film including a substrate and anisotropic semiconductor nanoparticles distributed on the substrate according to a periodic pattern. The semiconductor nanoparticles have an aspect ratio greater than 1.5, and the repetition unit of the pattern has a smallest dimension of less than 500 micrometer and includes at least one pixel. Also, a process for the manufacture of the electro-luminescent film, and a light emitting device that includes the electro-luminescent film.

摘要： A light sensitive device including a substrate and high pass filter semiconductor nanoparticles distributed on the substrate. The substrate includes at least one photosensor, and the semiconductor nanoparticles are high pass filters in UV-visible-NIR light range. The light sensitive device has a density of the semiconductor nanoparticles per surface unit of greater than 5×109 nanoparticles.cm−2. Also, a process for the manufacture of the light sensitive device, and an image sensor that includes the light sensitive device.
