采购商询盘内容

I'm looking for a photoluminescent dye or pigment that effectively absorbs UV light (≈ 350–380 nm) and green light (≈ 500–550 nm), while emitting strongly in the red region (≈ 600–700 nm). The ideal material should display high stability under prolonged UV and visible light exposure, meaning it shouldn't photobleach easily. Additionally, it should have good compatibility for dispersion in polymer matrices like PMMA, polycarbonate, or epoxy, and demonstrate efficient conversion with a high quantum yield. Could you provide detailed product specifications, including absorption and emission peaks, quantum yield, and stability/lightfastness? I'm also interested in pricing for small samples (50–100 g) as well as bulk orders (10–50 kg). Please include information on the minimum order quantity (MOQ), lead time, and packaging options. Availability of a technical data sheet (TDS) or MSDS would also be appreciated.
我正在寻找一种能够有效吸收紫外光（≈ 350–380 nm）和绿光（≈ 500–550 nm），同时在红光区域（≈ 600–700 nm）发出强光的光致发光染料或颜料。理想的材料应在长时间的紫外光和可见光照射下表现出高稳定性，这意味着它不易发生光漂白。此外，它还应具有良好的相容性，易于分散在聚甲基丙烯酸甲酯 (PMMA)、聚碳酸酯或环氧树脂等聚合物基质中，并表现出高效的转化率和高量子产率。 您能否提供详细的产品规格，包括吸收峰和发射峰、量子产率以及稳定性/耐光性？我还想了解小样品（50-100克）以及批量订单（10-50千克）的价格。请提供最低订购量（MOQ）、交货时间和包装选项等信息。如能提供技术数据表（TDS）或材料安全数据表（MSDS），我们将不胜感激。
