LUMINOPHORE COMPOSITION FOR UV-VISIBLE LIGHT CONVERSION AND LIGHT CONVERTER OBTAINED THEREFROM |
摘要 |
A luminophore composition comprising amorphous aluminoborate powders is disclosed. The composition is obtainable by preparing an aluminoborate resin by a wet chemical route based on precursors solutions substantially free from monovalent and divalent cations; drying the resin to obtain a solid; grinding the solid to obtain a powder; pyrolyzing the powder at a pyrolysis temperature lower than the crystallization temperature of the composition; and calcinating the powder so pyrolyzed at a calcination temperature lower than the crystallization temperature of the composition. Furthermore, a process for the preparation of said composition is disclosed. The composition is particularly suitable for use in solid-state lighting, and for example for converting UV light into warm white visible light. |
