Photoluminescence spectrometer (Flex One) / Spectrometer systems

Flex One, the latest in microspectrometers is a fully integrated, versatile and cost effective microspectrometer. It combines a microscope head directly coupled to a high-performance, triple gratings, imaging spectrometer

Photoluminescence spectrometer (Flex One) summary

Photoluminescence (PL) is the light emission from a material under the excitation by ultraviolet, visible or near infrared radiation.

In semiconductor luminescent property measurements, the sample (e.g. GaN, ZnO, GaAs, etc.) was usually excited by a laser (with a wavelength of 325 nm, 532 nm, 785 nm, etc.), and its PL spectrum is measured to analyze the optical physical properties, such as the band gap width.

Photoluminescence is a high sensitivity, non-destructive analysis method, which can provide the information about the structure, composition and surrounding atomic arrangement of materials. Therefore, it is widely used in physics, material science, chemistry and molecular biology and other related fields.
