Antireflective sub-wavelength structures for improvement of the extraction efficiency and color rendering index of monolithic white light-emitting diodeYiyu Ou
Department of Photonics Engineering, Technical University of Denmark, 2800 Kgs Lyngby, Denmark
Opt Express 19:A166-72. 2011..The CRI of the monolithic white LED could be improved from 92.68 to around 94 by applying a cylinder structure, and the CCT could be modified in a very large range with appropriate design of the cylinder structure...
Broadband and omnidirectional light harvesting enhancement of fluorescent SiCYiyu Ou
Department of Photonics Engineering, Technical University of Denmark, Lyngby DK 2800, Denmark
Opt Express 20:7575-9. 2012..The antireflective sub-wavelength structures on fluorescent 6H-SiC could also preserve the luminescence spectral profile at a large emission angle by eliminating the Fabry-Pérot microcavity interference effect...
Omnidirectional luminescence enhancement of fluorescent SiC via pseudoperiodic antireflective subwavelength structuresYiyu Ou
Department of Photonics Engineering, Technical University of Denmark, Lyngby, Denmark
Opt Lett 37:3816-8. 2012..The angle-resolved photoluminescence study presents a considerable omnidirectional luminescence enhancement with an integral intensity enhancement of 66.3% and a fairly preserved spatial emission pattern...
