Moreover, our powders adapt easily to the customer process: We make sure that activators are homogeneously distributed in the garnet lattice, in order to target maximum quantum efficiency. Baikowski® products reach a high sintering reactivity without sintering aid. We provide nanophosphors and specialty powders for light conversion. Tape casted YAG ceramic converting blue LED into warmer light Processability of Baikowski® powders for light conversion Lasers for wavelength conversion properties (undoped YAG).You can find light conversion phosphors in multiple applications, such as: Ce, Pr, Gd… for ceramic light converters & encapsulated phosphorsĪpplications with light conversion phosphors.Moreover, we formulate YAGs and LuAGs products to unique customer requirements with a variety of dopants: Thus, you will obtain a dense ceramic at low sintering temperature with the finest microstructure (low thickness & controlled light diffusion). Submicronic control of particle size & particle size distribution.It optimizes optical properties ( quantum efficiency…) Optimized distribution of activators within the lattice.In addition, Baikowski’s YAGs and LuAGs show: Embedded phosphors could require nanoscale material in order to answer the needs of new semiconductor design emerging (3D LED for example).That is why ceramic converters are essential when it comes to high power LEDs and lasers. They provide very few alterations of the conversion and optimize diffusion. Unlike polymer matrix, ceramic converters allow high temperatures into the system.Our phosphors show outstanding properties for various applications: High power LED chip made with ceramic light converters Properties of phosphors We can also add other dopants upon request. We dope our nano-phosphors with Cerium for blue LED conversion. Baikowski® provides Phosphors, designed for high performances of conversion. The light conversion occurs either by a mix of powders dispersed in a matrix, or a ceramic convertor. The light conversion happens when a wavelength is transformed into another wavelength or more. There are mainly UV and blue native LEDs.
That is why the LED often ranks as a “monochromatic” emitter. The semiconductor (heart of the LED) emits in a narrow spectrum. In the vacuum, the visible spectrum is between 380nm and 750nm.Ī Light-Emitting Diode, mostly known as LED, is an electronic device that emits light when crossed by an electrical current. Visible light gathers all the electromagnetic waves that are detected by human vision. Then, find a focus on inorganic luminescent materials: the phosphors. How does light conversion happen with phosphors?įirstly, find a few definitions in order to understand what is the light conversion.
