Highly textured zinc aluminate: Nd, Ce films over sapphire for NIR emitting applications

Cost-effective screen printing approach for Ce/Nd-doped ZnAl2O4 films: tuning crystallinity induced by the substrate

“…In our previous paper, 36 we demonstrated that luminescent (hk0)-textured ZnAl 2 O 4 :Nd,Ce sub-micron films over sapphire substrates can be successfully obtained. To further exploit the potential of the proposed screen-printing technique and obtain better properties using more versatile substrates, polycrystalline alumina substrates are employed.…”
