With the development of new and higher performing consumer electronic products, the industry requires more stable and longer lasting photoluminescent and phosphorescent aluminate-based pigments that can be reused many times with no change in the performance. Photoluminescent pigments are used in applications like coating, printing ink, paints,  and printing pastes, amongst others. We have developed alumina products suitable for mixing with other inorganic materials, such as ZnS, for enhanced performance.
