Application of Phosphorescence Materials for Investigation of Oxygen Presence in Packages
S Fatemeh Yari Gharahnaz, Esmaeil Heydari,
year 27, Issue 2 (ICOP & ICPET 2021 2021)
Abstract
Oxygen is essential for living creatures however it could be detrimental to food. Here, we investigate the application of phosphorescence material to study the oxygen presence in food packages. Therefore, a disk-shape film of platinum complex as phosphorescence materials in polystyrene matrix is prepared. 410nm laser beam is used for excitation due to its absorption spectrum. There is considerable change in the phosphorescence intensity in the test box filled with and without oxygen.
