Fluorescence is the light emitted by a substance when it absorbs light or other electromagnetic radiation. A common example is the absorption of ultraviolet light by a substance that emits fluorescence in the visible band. Fluorescence has a wide range of applications in high-resolution optics, phosphor reflection, medical applications, photolytic media reactions, UV adhesive curing, and specialty lighting.Depending on the material, it can be divided into fluorescence spectral measurements for liquid materials ,solid materials, powder materials.

For the measurement of liquid materials,the cuvette is usually used for sampling and the fluorescence spectrum of excitation is measured in the direction of 90 degrees of light source incidence. For solid material measurements, a miniature fiber optic holder is used so that the incident light from the light source and the resulting fluorescence form a 45-degree angle. When measuring powdered materials, a hemispherical integrating sphere is designed and the test sample is placed at the center of the sphere, through which the scattered fluorescence is collected and then transmitted to the spectrometer for measurement.
