The EX-1000 fluorescent material excitation spectrum and thermal quenching analysis system can measure the excitation spectrum characteristics and emission spectrum characteristics of fluorescent materials, which is helpful for screening effective excitation light sources, or improving the excitation spectrum characteristics of fluorescent materials under the premise of specific excitation light sources. to achieve higher excitation-to-luminescence conversion efficiency. It can also measure the luminescence characteristics (thermal quenching characteristics) of fluorescent materials under real Operating Conditions (high temperature conditions) to avoid using their normal temperature characteristics to replace the real Operating Conditions and ensure the luminous quality of fluorescent materials.
The EX-1000 fluorescent material excitation spectrum characteristics and thermal quenching analysis system is a comprehensive phosphor measuring instrument that can be used for the research and development of various phosphors such as rare earth three-color phosphors for lamps and rare earth yellow phosphors for white light LED lamps. and quality control to provide comprehensive and objective measurement data.
