Long afterglow characteristics of thin film phosphor fabricated by laser ablation

The influence of different species of gases on the luminescent and structural properties of pulsed laser-ablated Y2O2S:Eu3+ thin films

“…Light emission from the spherical-shaped phosphor particles as excited by the electron beam is more intense due to the fact that much less photons encounter total internal reflection [29,30]. The increase in the deposition pressure is reported to have caused an increase in the connectivity (agglomeration) between particles due to sintering of small particles [31]. This would eventually lead to grain growth at high enough pressure.…”

Fabrication and study of properties of the PLA/Sr2MgSi2O7:Eu2+, Dy3+ long-persistent luminescence composite thin films

“…LPL materials are usually prepared and investigated in the form of powders and films. LPL films have potential applications in many technological aspects, including displays [8], sensors for stress [9] and temperature [10,11], and so on. Because of the poor adhesion between the luminescence films and substrates, many high energy methods following annealing are chosen to prepare the luminescence films.…”

“…For instance, K. Kato and coworkers [12] successfully prepared SrAl 2 O 4 :Eu LPL films by RF sputtering. K. Sato et al [10] and P. D. Nsimama et al [13] prepared SrAl 2 O 4 :Eu,Dy LPL films by laser ablation and pulsed laser deposition following annealing, respectively. However, high energy methods are not only costly and complicated, but also have the risk of damaging film's luminescent properties during annealing [14].…”

Preparation and characterization of fiber-textured SrAl2O4:Eu films grown using a homo-buffer layer

“…Over the last few years there has been significant research interest in the growth and characterization of SAOE thin films because of the promise for applications in display devices, temperature sensors and so on [2][3][4][5]. Until now, SAOE films have been prepared by various methods, including ion-beam evaporation [6], laser ablation [2], pulsed laser deposition [7], the sol-gel process [8] and RF sputtering [9]. Furthermore, as the physical properties of polycrystalline thin films are greatly influenced by their crystallographic orientations (texture), it is desirable to be able to prepare a textured film [10].…”
