# Optical & Phosphor Materials Source: https://powdchem.com/products/laboratory-powders/optical-phosphor-materials/ Page type: Material category Laboratory powders Phosphor, luminescent and optical-material powder inquiries, specified around host chemistry, dopant and the intended optical evaluation. [Browse 6 materials]() [Ask about supply]() [Image: Powder material specimens; appearance reference]() ## Choose a material ### Garnet and phosphor powders Separate the host material from the doped phosphor. Include the dopant and excitation/emission conditions needed to assess an optical result. #### Yttrium aluminum garnet powder yttrium aluminum garnet powder (YAG; Y3Al5O12) [Selection guide]() [Ask about this material]() Y3Al5O12 #### Cerium-doped YAG phosphor powder cerium-doped YAG phosphor powder (Ce:YAG) [Selection guide]() [Ask about this material]() (Y(1-x)Cex)3Al5O12 #### Strontium aluminate phosphor powder strontium aluminate phosphor powder (SrAl2O4-based; activator is grade-specific) [Selection guide]() [Ask about this material]() SrAl2O4-based; phase/dopant varies ### Optical fluoride powders CaF2, MgF2 and LiF are separate chemical choices. Confirm powder form and the impurity and moisture limits required by the intended optical process. #### Calcium fluoride powder calcium fluoride powder (CaF2; fluorite structure when confirmed) [Selection guide]() [Ask about this material]() CaF2 #### Magnesium fluoride powder magnesium fluoride optical material powder (MgF2) [Selection guide]() [Ask about this material]() MgF2 #### Lithium fluoride powder lithium fluoride powder (LiF) [Selection guide]() [Ask about this material]() LiF ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Host & activator** Specify the host phase and dopant, not just the requested color. Keep nominal chemistry and grade-specific composition distinct. **Optical test basis** Provide excitation/emission needs and the conditions for spectral, color-coordinate or efficiency comparison. **Process compatibility** Discuss particle size, coating, matrix, loading and thermal or humidity exposure in the intended device or formulation. ## Before you choose **Is a phosphor's visible powder color enough to select a grade?** No. The host/activator system, excitation conditions and processing environment need to match the application. Illustrative powder photography cannot establish emitted color or spectral performance. **What does this directory cover?** LED packages, lamps and finished optical components are not powder products. Functional pigments are listed separately. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Host phase and dopant/activator - Excitation/emission and measurement conditions - Particle size and surface treatment - Matrix, exposure conditions and evaluation quantity ### Quantity, samples and documents Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums. We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements. [How we coordinate documents]() [Samples and testing]() [Send a material request]() ## Applications to explore.
