  • METHOD AND SYSTEM FOR DETERMINING A COLOR FORMULA
    Publication number: 20160321546
    Abstract: The invention relates to a method to determine a formula for a sample color matching a target color, based on an obsolete color formula, based on a given range of tinting bases. According to the proposed method, a color prediction model is used to calculate a distance between respective color parameters of a candidate color formula and the color parameters of the target color, and a genetic algorithm is used to obtain the formula for the sample color out of a population of candidate color formulas, wherein a distance of respective color parameters of a candidate color formula of the population of candidate color formulas to the color parameters of the target color is minimized by the genetic algorithm by iterative steps of mutation/crossing-over and selection of candidate color formulas that fit best to a fitness criterion, until a pre-given stopping criterion is fulfilled which automatically leads to a candidate color formula which is kept as the sample color formula.

  • Precursor compounds of alkaline earth metal or rare earth metal aluminates method production and use thereof particularly as precursors for luminophores
    Patent number: 7625546
    Abstract: The invention relates to alkaline-earth or rare-earth metal aluminate precursor compounds, to their method of preparation and to their use in particular as phosphor precursors. These alkaline-earth or rare-earth metal aluminate precursor compounds are essentially crystallized in the form of a transition alumina and in the form of substantially spherical and chemically homogeneous particles including pores whose mean diameter is of at least 10 nm.
