Pressure induced emergence of visible luminescence in : Effect of structural distortion in optical behaviour
Debabrata Samanta, Pinku Saha, Bishnupada Ghosh +4
We report emergence of photoluminescence at room temperature in trigonal at high pressures. Enhancement in intensity with pressure is found to be driven by increase…

Water incorporation in Fe-containing wadsleyite from density functional theory at extreme conditions
Tilak Das, Swastika Chatterjee, Tanusri Saha-Dasgupta
Using first-principles density functional theory (DFT), we studied the issue of water incorporation in iron bearing wadsleyite (MgSiO)mineral at transition zone pressures a…
