White light is not an individual color of the spectrum. White light is comprised of all the colors that make up the visible light spectrum. What exactly is white light? White light is electromagnetic radiation or waves. White light is comprised of all the frequencies and wavelengths of the vi...
The photopic eye-sensitivity curveV(λ) is utilized as the dominant portion of white light spectra. Emission spectra of a blue InGaN light-emitting diode (LED) and a red AlInGaP LED are added to the spectrum ofV(λ) to match white color coordinates. It is demonstrated that at the ...
Spectral glasses enable a pragmatic approach to evaluate the colour rendering of light. This technique could help architects, interior and lighting designers to analyse quickly how light reproduces colours on objects. The film by Thomas Schielke covers vivid impressions of our architectural and urban ...
7 The spectrum of white light is made up of seven colours.(a)Fig. 7.1 shows a partially-completed spectrum. Two labels are missing.violet indigo green orange red Fig.7.1(i) On Fig. 7.1, write the name of the missing colour in each blank space.[2](i) On Fig. 7.1, indicate the di...
White organic light-emitting diode(WOLED)is of growing interest because of its potential applications in full-color displays and solid-state lighting sources.Now,it is still a big challenge,for a simplified WOLED,to realize low cost and high color rendering index(CRI)simultaneously.In this work...
Tailored light sources have greatly advanced technological and scientific progress by optimizing the emission spectrum or color and the emission characteristics. We demonstrate an efficient spectrally broadband and highly directional warm-white-light emitter based on a nonlinear process driven by a cheap, ...
Calculated linear 1 − Rspectra of the (6,5)- (a), (7,5)- (b) and mixed (6,5)/(7,5) (c) microcavities. Inc, the diagonal slice from the measured two-dimensional white-light (2DWL) spectrum in Fig.2f, top (light blue line) is overlaid with the calculated spectrum (...

(Figure 3b). Therefore, a tunable color spectrum including white light can be obtained by combining the two emission bands located at approximately 446 and 550 nm in this SPBO_Cl:0.04Eu2+solid-solution phosphors. The change in the emission ratio may be attributed to the higher number ratio ...
