Excitation, Fluorescence, 3D Fluorescence Spectrum of Lamp Phosphor for LED (Yellow)

Excitation Spectrum of Lamp Phosphor for LED (Yellow)

INTRODUCTION


In the daylight white type LED, the light emitted from the blue LED and yellow light emitted from the phosphor are synthesized to produce the color close to the color of fluorescence lamps. This time, the fluorescence properties of the yellow phosphor used in the daylight white type LED lighting were analyzed. The manufacturers of LED control the color tones by using newly developed phosphors so as to produce unique LED emission colors. By analyzing the fluorescence spectra, the information of the colors emitted by phosphors can be obtained and thus, the analysis is useful for the research and development as well as for the quality control.


By using the spectral correction functions of the F-7000 spectrophotometer, the wavelength characteristics originating from the detection optical system (spectrophotometer, mirror, detector, etc) can be corrected and thus, the accurate spectrum analysis is possible.
