Solid state luminescent powders include LED powder luminescence measurement, fluorescent powders for tricolor lamps, and quantitative luminescence spectra of display materials. The reproducibility of their test data has always been a challenge for experimental personnel in scientific research and factory R&D departments.

This system is developed based on numerous existing international testing methods and means, and is used for quantitative testing of fluorescence spectra of luminescent powders. The data content includes: luminescence spectrum, external quantum efficiency, absolute (internal) quantum efficiency, color coordinates, color purity and color temperature, and color rendering index. Has excellent operability and data reproducibility.

Among them, the external quantum yield can be used as an alternative measurement item for relative luminescence intensity measurement, completely independent of absolute testing of standard samples, and can also be used as a monitoring method for standard sample testing and identification.

Other solid fluorescence testing applications, such as qualitative and quantitative testing of napkin fluorescein, also provide a simple, fast, and reliable method for rapid quality detection in the healthcare system. For more product and application information, please inquire.
