Alumina encapsulation on SrAl 2 O 4 : Eu 2+ , Dy 3+ phosphors by a new type of chemical precipitation process was reported for the first time to the best of our knowledge. X-ray fluorescent measurements revealed that using glycol instead of the distilled water as the disperse medium is helpful to al
As described herein, we prepared SrAl 2 O 4 :Eu 2+ , Dy 3+ phosphor using a domestic microwave oven operated at 2.45 GHz with 500 W in 30 min, processes with carbon reduction. Using carbon as the microwave absorber it generates thermal energy. Furthermore, heating with carbon can provide a reductive
