One of the best phosphorescent material known so far is SrAl2O4: Eu Dy has been synthesized by solid state method, different soft chemistry routes such as hydrothermal, coprecipitation method etc have been synthesized to enhance the afterglow properties of this material. No attempts were made so far to synthesize the aero/xerogel for these materials and study their afterglow properties, hence the objective of this Postdoc how this approach can impact the afterglow properties of this material

Multicolored emitting phosphors production via single step for solid state lightning application A promising general approach is proposed that enables the controlled reduction of dopants to tune the photoluminescence properties of single‐phase materials. The change of oxidation state of dopants in phosphor phases leads to different emission colors that can be finely tuned. Henceforth, multicolored phosphors could be obtained in one single step that could be applied for solid state lightning applications.

Simulation carried out via Finite Element Method to study the impact of stress and strain to on the physics of this material This project was related to the finite element simulation of the stress state of a coherent precipitate, its growth and the change of state of stress on the formation of an interfacial dislocation loop unsuitable. The critical radius was determined from simulations based on: (i) global energy minimum (r *) and (ii) the local force equilibrium along the radial direction (rc).
