For the first time, well-dispersed submicrometer-sized YVO(4):Eu(3+) hollow spheres were successfully synthesized though a surfactant-free method by employing Y(OH)CO(3):Eu(3+) colloidal spheres as a sacrificial template and NH(4)VO(3) as a vanadium source. The synthetic process mainly consists of two steps, i.e., hydrothermal reaction and acid erosion. By simply changing the amount of NH(4)VO(3) added, the textural parameters of the as-obtained hollow spheres, such as the inner diameter and shell-thickness, can be easily tuned. Moreover, double-shelled hollow spheres could also be obtained when the amount of NH(4)VO(3) was increased to a certain extent. Particularly, the amorphous colloidal spheres of the template could be completely consumed when the amount of NH(4)VO(3) was in large excess, giving rise to the direct formation of uniform hollow spheres without acid erosion. The possible formation process is discussed in detail. Under ultraviolet excitation, the obtained hollow YVO(4):Eu(3+) phosphors showed strong red emissions, and the Commission Internationale d'Eclairage (CIE) coordinates of the YVO(4):Eu(3+) phosphors were closely related with the textural parameters such as the inner diameter, shell-thickness and number of shells, indicating a size-dependent characteristic.

“…Solid photoluminescent materials were generally synthesized by high temperature solid reaction method, but the method was proved to be imperfect. Along with the development of science and technology, some new preparations methods get widely used in synthesized photoluminescent powders like hydrothermal method [2], microwave method [3], precipitation [4], sol-gel, combustion method [5] and other methods [6]. Among them, microwave method is the distinctive one in that it overcomes the shortcomings of high temperature solid reaction method and possesses characteristic as fastness, high efficiency, uniform heating, which could significantly improve the photoluminescent property.…”

YVO4:Eu3+ phosphors were prepared by microwave hydrothermal method in this work. YVO4:Eu3+ phosphors were probed by photoluminescence (PL), X-ray powder diffraction (XRD) and scanning electron microscope (SEM). The effects of different preparation conditions on the photoluminescence, the structure and the morphology of YVO4:Eu3+ phosphors were studied. The experiment results show that the pH value and the Eu3+ doping amount have some important effect on the photoluminescence and the morphology of YVO4:Eu3+phosphors.

“…If videography methods can capture the emission of the NPs themselves, this would clearly show when and where the NPs are generated. Eu 3+ -doped yttrium vanadate (YVO 4 :Eu 3+ ) is a red-emitting phosphor under UV excitation, [29][30][31] and its NPs can be produced through PLAL. [32][33][34][35] Therefore, we used YVO 4 :Eu 3+ as a target instead of a metal sample, and carried out observations of UV-induced photoluminescence from YVO 4 :Eu 3+ NPs following laser ablation in water.…”

Understanding the timing and location of nanoparticle (NP) generation during pulsed laser ablation in liquid is important for their fabrication. We report on high-speed videographic observations of UV-induced photoluminescence from YVO4:Eu3+ NPs following laser ablation in water. YVO4:Eu3+ is a red-emitting phosphor under UV excitation. A white mist-like region of low brightness, thought to be emissions from these NPs, appeared at the target surface’s center after laser irradiation. The NPs appeared to be diffuse within the first generated bubble during the expansion phase and gathered in its center during the shrinkage phase, remaining within the bubble until its collapse.
