Red phosphor powder for CFLS
Dongtai Tianyuan Fluorescent Material Co., Ltd. supplies red luminescent phosphor powder specially formulated for compact fluorescent lamps. The grade has a median particle diameter (d50) of ≤ 6.0 µm and passes through a 350 mesh screen, ensuring uniform coating on lamp interiors. Its bulk density does not exceed 5.15 g/cm³, which aids consistent dosing during manufacturing. The emitted light peaks at 611 nm with a spectral semi‑width of 62 nm, delivering a warm red hue. Measured colour coordinates are x = 0.650, y = 0.345, and relative luminosity matches 100 % of the standard reference sample. The material contains no visible mechanical impurities and is sealed in moisture‑resistant plastic bags of 2 - 3 kg each.
Red phosphor powders for CFLs are typically rare‑earth based compounds such as europium‑doped yttrium oxide, with industry‑standard particle sizes ranging from 5 to 7 µm, so the supplied ≤6.0 µm d50 aligns with common practice. Standard bulk densities for comparable grades fall between 5.0 and 5.3 g/cm³, making the listed ≤5.15 g/cm³ a typical value. A main emission peak between 610 nm and 620 nm and a semi‑width around 60 nm are regarded as standard for achieving the desired red colour rendering in CFLs. Moisture‑resistant packaging is the usual method to preserve phosphor performance during storage and transit, and a 2 - 3 kg bag size matches typical bulk handling requirements.
Buyers such as lamp manufacturers and component distributors generally request confirmation of minimum order quantity, lead time and Incoterms before finalising a contract. The supplier indicates that the powder is shipped in sealed, moisture‑proof bags, but exact pricing, MOQ and delivery schedule should be verified directly with Dongtai Tianyuan.

Dongtai Tianyuan Fluorescent Material Co., Ltd. is located in the Sizao Industrial Zone, Yancheng Dongtai, Jiangsu Province, China. The company is classified as an imported‑tier supplier with a harbour trust tier, although its current response rate is recorded as 0.00, indicating that trade inquiries may require proactive follow‑up. The firm lists red phosphor powder for CFL applications as its primary product offering, emphasizing compliance with industrial luminescence standards.
As a specialist in fluorescent materials, the supplier focuses on rare‑earth based phosphors that meet the optical performance requirements of high‑volume lamp manufacturers. While the public profile does not disclose production capacity, years of operation, or client references, the listed specifications suggest adherence to typical quality controls for luminescent powders. Potential buyers should request any available test reports or certificates directly from the company to confirm conformity with their own quality systems.
Red phosphor powder is a critical luminescent material used in compact fluorescent lamps (CFLs) to produce warm red visible light when excited by UV radiation from the lamp's mercury arc. This grade features a median particle diameter of d50 ≤ 6.0 μm and passes through a 350 mesh/cm screen, ensuring consistent coating uniformity and optical performance in CFL manufacturing. With a bulk density of ≤ 5.15 g/cm³ and controlled relative luminosity, it meets stringent industrial quality standards for high-volume lamp production. Red phosphor powder is supplied in sealed, moisture-resistant packaging to preserve luminescence properties during storage and international transit.

Sourcing Red phosphor powder for CFLS from Dongtai Tianyuan Fluorescent Material Co., Ltd. - China Import Guide
Before placing an order, verify that the powder meets the impurity limits required for your lamp design, and request a particle‑size distribution report to confirm the ≤6.0 µm median value. Ask for a certificate of luminescence performance that demonstrates the 100 % relative luminosity against the standard sample, as well as any available material safety data sheets. These documents help ensure the product will integrate smoothly into your production line.
Clarify the preferred Incoterms, typical lead time and payment conditions with Dongtai Tianyuan prior to contract signing. Because the listed response rate is currently zero, allow extra time for correspondence and consider arranging a video call to discuss logistics. Confirm whether the supplier can accommodate container‑level shipments or prefers smaller batch deliveries, and align the shipping schedule with your inventory planning.
Arrange for an independent inspection of the sealed bags upon arrival, focusing on moisture ingress, packaging integrity and visual impurity checks. Request a third‑party certificate of analysis that includes bulk density, particle size and spectral data to validate the supplied specifications. Retain the material safety data sheet and any compliance certificates for customs clearance and downstream quality assurance.
