A Novel Orange-Red Emitting ZnB4O7:Eu3+ Phosphor with Urchin-Like Nanostructure by Hom Nath Luitel, Rumi Chand, Takanori Watari

“…The ZnB4O7:Eu3+ phosphors were efficiently excited by ultraviolet (UV ~ 254 nm) to visible light of ~ 220 to 450 nm and exhibited intense orange-red emission consisting of main peaks at 590, 615, and 695 nm due to the charge transfer in the host and f→f transitions (5D0 to 7F1,2,4) of the Eu3+ ions. Effect of the Eu3+ ions concentration on the photoluminescence (PL) emission intensity was investigated and it was found that 5 at% Eu3+ is the optimum concentration. …”

The mechanisms of fiber flax adaptation to high soil acidity (a review) by N. V. Kishlyan, N. V. Melnikova, T. A. Rozhmina

“…Using high-through put sequencing and quantitative PCR, a change in the expression of genes and microRNAs in flax plants was revealed in response to the toxic effect of aluminum ions. Using flax genotypes contrasting in acid resistance, an increase in the expression of genes encoding UDP-glycosyltransferases (UGT) and glutathione-S-transferases (GST) was established under aluminum stress. …”
