Abstract:
Provided according to embodiments of the invention are methods of making a Ca1-x-ySrxEuyAlSiN3 phosphor composition that include selecting a relative color point; determining Eu and Sr concentrations based on predetermined values to obtain the selected relative color point; and making the Ca1-x-ySrxEuyAlSiN3 phosphor having the determined Eu and Sr concentrations. Also provided are methods for determining concentrations of Sr and Eu in a Ca1-x-ySrxEuyAlSiN3 phosphor that will achieve a relative color point. Related computer products are also disclosed.
