The role of structural order–disorder for visible intense photoluminescence in the BaZr0. 5Ti0. 5O3 thin films
The nature of the intense visible room temperature photoluminescence of BaZr0. 5Ti0. 5O3
non-crystalline thin films is discussed in the light of experimental results and theoretical
calculations. The photoluminescence measurements reveal that the emission intensity
changes with the degree of disorder in the BaZr0. 5Ti0. 5O3 lattice. First principles quantum
mechanical techniques, based on density functional theory at B3LYP level, have been
employed to study the electronic structure of a crystalline model and of structurally …
