ChemInform Abstract: Eu²⁺‐Doped M₂SiO₄ (M: Ca, Ba) Phosphors Prepared by a Rapid Microwave‐Assisted Sol—Gel Method: Phase Formation and Optical Properties.

Abstract

The green-emitting title phosphors a prepared by an optimized fast and energy-efficient citrate based sol-gel reaction with subsequent combustion in a domestic microwave oven leading to high quality materials in less than 25 min of final heating time. The samples, especially Ba 2 SiO 4 :Eu 2+ , show good quantum yields and are suitable for applications in green phosphor-converted light emitting diodes, or as green components in phosphor blends. -(BIRKEL*, A.; DECINO, N.

Rapid microwave-assisted preparation of binary and ternary transition metal sulfide compounds

“…Microwave (MW) irradiation and MW-assisted heating have been shown to greatly reduce the time and energy required to 40 prepare inorganic materials [33]. MW preparation has been reported for ceramics, including phosphors for solid-state lighting [34,35], materials for catalysis [36] and batteries [23,37] just 5% of the conventional furnace preparation time. [40,41].…”
