Broadband white light emission from Ce:AlN ceramics: High thermal conductivity down-converters for LED and laser-driven solid state lighting

Autor: A. T. Wieg, E. H. Penilla, C. L. Hardin, Y. Kodera, J. E. Garay

Publikováno v: APL Materials, Vol 4, Iss 12, Pp 126105-126105-8 (2016)

We introduce high thermal conductivity aluminum nitride (AlN) as a transparent ceramic host for Ce3+, a well-known active ion dopant. We show that the Ce:AlN ceramics have overlapping photoluminescent (PL) emission peaks that cover almost the entire

Transmitting, emitting and controlling light: Processing of transparent ceramics using current-activated pressure-assisted densification

Autor: Yasuhiro Kodera, C. L. Hardin, Javier E. Garay

Publikováno v: Scripta Materialia. 69:149-154

We review recent advances in using current-activated pressure-assisted densification (CAPAD) for fabricating polycrystalline ceramics that are transparent to visible and infrared light. In addition, we discuss important one-dimensional (vacancies), t

The role of scattering and absorption on the optical properties of birefringent polycrystalline ceramics: Modeling and experiments on ruby (Cr:Al2O3)

Autor: Dean R. Evans, Elias H. Penilla, Sergey Basun, Javier E. Garay, C. L. Hardin, Yasuhiro Kodera

Publikováno v: Journal of Applied Physics. 119:023106

Light scattering due to birefringence has prevented the use of polycrystalline ceramics with anisotropic optical properties in applications such as laser gain media. However, continued development of processing technology has allowed for very low por
