In this paper, preparation of SrAl2O4:Eu,Dy luminescent pigment has been investigated. Coprecipitation as a low cost and facile method was selected. X-ray diffraction patterns indicated the formation of SrAl2O4:Eu,Dy phase through calcinations process above 800 °C. Moreover, a few amount of silica caused the structural transformation to alumina silicate phase. Transparent glaze which consist of...

Commercially mature “Bartlett” pears for this study were obtained from local commercial packing facilities. In the first year, pears were packed in modified atmosphere bags and placed in boxes or packed normally (control) with an individual paper wrap around each pear plus a polyethylene liner in the box.
