Hydrothermal synthesis of lanthanide orthovanadate: EuVO4 particles and their fluorescence application

Abstract

Lanthanide orthovanadate erythrocyte-like EuVO 4 particles were obtained via a facile, environmentally friendly hydrothermal process and were demonstrated to have an affinity for histidine (His) and the common protein BSA. Fourier transform infrared (FTIR) and Raman spectroscopy indicated an interaction between EuVO 4 and His, as well as BSA. Due to its unique structure, the anionic group (VO 4 32 ) served to directly combine with His or BSA, while the cation (Eu 3+ ) was used as a stable fluorescent monitor. The traditional technically-demanding lanthanide particle surface functionalization can be neglected for the first time, which greatly simplified the preparation of lanthanide particles. Based on the affinity of EuVO 4 and proteins, the interaction between EuVO 4 and member proteins in vitro had been confirmed by confocal microscopy, which might find potential application in fluorescent monitors.

Equation of state and electronic properties of EuVO4: A high-pressure experimental and computational study

“…It has been concluded that zircon-type EuVO 4 is a valuable red phosphor [3], because it exhibits a strong red emission under both near UV and visible-light excitation. It has also been considered for application in white LEDs [4]; its fluorescence can be used in biology and medicine for monitoring the cells [5]. Potential application has been reported as an ionic conductor [6] and as a material for detection of H 2 O 2 [7].…”

“…In addition, it is used as a fluorescent biological label for the detection of Na${}^{+}$ channel dynamics on cell membranes [77]. EuVO${}_4$ might be suitable to track biological systems, such as histidine and bovine serum albumin [78]. …”

Nanostructured tetragonal crystal NdVO4 for the detection of liquefied petroleum gas

“…Au et al synthesized NdVO 4 particles using the citrate method, and their catalytic properties were studied by oxidative dehydrogenation of propane. The effects of Eu3 + doping on morphology and fluorescent properties of neodymium vanadate nanorod-arrays were studied [17,18]. Fan et al synthesized single crystalline tetragonal nanorods of NdVO 4 through hydrothermal method and explained the growth mechanism [19].…”
