  • Patent number: 11926775
    Abstract: This specification discloses methods of enhancing the stability and performance of Eu2+ doped narrow band red emitting phosphors. In one embodiment the resulting phosphor compositions are characterized by crystallizing in ordered structure variants of the UCr4C4 crystal structure type and having a composition of AE1?xLi3?2yAl1+y?zSizO4?4y?zN4y+z:Eux (AE=Ca, Sr, Ba, or a combination thereof, 0<x<0.04, 0?y<1, 0<z<0.05, y+z?1). It is believed that the formal substitution (Al,O)+ by (Si,N)+ reduces the concentration of unwanted Eu3+ and thus enhances properties of the phosphor such as stability and conversion efficiency.

  • Patent number: 11891408
    Abstract: The present invention relates to the application of lithium 4-methoxyaniline in catalysis of the hydroboration reaction of an imine and a borane. A catalyst, a borane and an imine are successively stirred and mixed until uniform, reacted for 1 to 2 hours, and then exposed to air so as to stop the reaction, and the reaction liquid is subjected to decompression to remove a solvent therein, so as to obtain a borate with different substituents. The lithium 4-methoxyaniline disclosed in the present invention can catalyze the hydroboration reaction of an imine and a borane in a high activity manner at room temperature, wherein the amount of the catalyst is merely 4-5 mol % of the molar amount of the imine, and the yield of the reaction can reach 90% or more. The yield of a borate with different substituents can reach 99% with mild reaction conditions under an optimized condition.
