[Influence of lighting sources spectra on the human visual brightness identification under the mesopic vision].

Based on the MOVE models and the measurement of emission spectra of various light sources, the photopic function weights x and the mesopic equivalent brightness of human visual spectral luminous efficiency in different background brightness were calculated. Results showed that in the mesopic scope, human visual function peak value gradually increases with the brightness decreasing, and is moving towards the short-wave direction. The change rate is inversely proportional to the s/p index.

[Fabrication and luminescent properties of Dy3+ doped Sr(1-x)Ca(x)MoO4].

Dy3+ doped Sr(1-x)CaxMoO4 phosphors were prepared by solid state method in the present paper.
