Photoluminescence Microscopic Spectrometer Zolix Instruments CO.,LTD

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 etc.. Photoluminescence is a high sensitivity, non-destructive analysis method, which can provide the information about the structure, composition and surrounding atomic arrangement of...
