Fluorescence Spectrometer

Fluorescence spectroscopy is an investigative method based on the fluorescence properties of the sample, and is used for quantitative measurements of chemical products. Fluorescence spectroscopy can provide information such as excitation spectrum, emission spectrum, peak position, peak intensity, quantum yield, fluorescence lifetime, fluorescence polarization, etc., which is the basis for qualitative and quantitative fluorescence analysis. Fluorescence spectra are divided into excitation spectra and emission spectra.

Sample Requirements

• The sample must have fluorescence / phosphorescence properties. You can observe whether the sample emits light under the irradiation of a UV laser lamp or a UV dark box.
• Powder samples: fluorescence lifetime, steady state (excitation or emission spectrum), quantum yield, up-conversion 980, each test requires 50~100 mg.
• Liquid samples: at least 5 mL.
• Block / film sample size requirements: 1×1 cm~2×2 cm, thickness: 0.1 cm.

Application

• Test project:
• Routine test (RT): excitation spectrum, fluorescence emission spectrum, phosphorescence/delayed fluorescence emission spectrum, upconversion luminescence, fluorescence lifetime, fluorescence quantum yield
• Variable temperature fluorescence spectrum, variable temperature lifetime
• Research on optoelectronics materials and proteins
