| Abstract: | The influence of the polarized state of blue light on light scattering in InGaN blue chip nano-crystal luminescent glass for solid state lighting is investigated.Based on Rayleigh-Debye approximation theory,theoretical relationships between the light scattering turbidity and wavelength of the incident light,radius and refractive index of the nano-crystals are established to simulate the situations in yttrium aluminate garnet(YAG),silicate and oxynitride based luminescence glass.It is revealed that the scatt... |
