Patent number: 9109163Abstract: Optical conversion layers based on semiconductor nanoparticles for use in lighting devices, and lighting devices including same. In various embodiments, spherical core/shell seeded nanoparticles (SNPs) or nanorod seeded nanoparticles (RSNPs) are used to form conversion layers with superior combinations of high optical density (OD), low re-absorbance and small FRET. In some embodiments, the SNPs or RSNPs form conversion layers without a host matrix. In some embodiments, the SNPs or RSNPs are embedded in a host matrix such as polymers or silicone. The conversion layers can be made extremely thin, while exhibiting the superior combinations of optical properties. Lighting devices including SNP or RSNP-based conversion layers exhibit energetically efficient superior prescribed color emission.Type: GrantFiled: January 27, 2011Date of Patent: August 18, 2015Assignee: YISSUM RESEARCH DEVELOPMENT COMPANY OF THE HEBREW UNIVERSITY OF JERUSALEM LTD.Inventors: Hagai Arbell, Uri Banin
