In order to enhance the UV-response of CCD & CMOS sensors

an piece of UV-enhanced film is coated on the photosurface of CCD & CMOS sensors

which is a very useful method to enhance the UV-response of CCD & CMOS sensors. Zn2SiO4:Mn

owing the properties of small particle size

well-stabilizing and high-luminescence QE

has very wide useful vistas in the field of enhance UV-response of CCD & CMOS sensors. This experiment prepared the Zn2SiO4:Mn thin-films on quartz substrates by the spin-coated method

and measured the transmission spectrum

absorption spectrum

excitation and emission spectrum of Zn2SiO4:Mn thin-films. The result show that the thin-film has steady low transmission when the wavelength less than 300nm and steady high teansmission when the wavelength more than 300nm. It is to say that the thin-film can absorb light which wavelength less than 300nm but can’t absorb more than 300nm. More importantly

the excitation peak of the film is at 265nm and the emission peak is at 525nm. Meanwhile this experiment has analyzed the thickness and smoothness of the Zn2SiO4:Mn thin-films.The result show that the Zn2SiO4:Mn thin-film is a kind of nice thin-film which used to enhance UV-response of CCD & COMS sensors.
