Hypochlorous acid (HOCl) and hypochlorite anions (−OCl) are nonselective oxidants produced by activated neutrophils and monocytes and play an important role in the formation of immune response of a living organism. At the same time, because of the

LnVO4:Eu3+ (Ln = Gd, Y, La) nanoparticles (NPs) of different sizes have been synthesized by citrate and citrate-free routes. NPs of both types reveal photobleaching, i.e. decrease in Eu3+ emission under UV-light irradiation. The efficiency of the pho
