“…Direct sensitization of the Mn 2+ emission by Ce 3+ ions is not feasible in this lattice. [ 11,12 ] As was shown before, Ce 3+ in contrast is a good sensitizer for Gd 3+ , which in turn sensitizes Mn 2+ . [ 13 ] In the pentaborate structure, both Mn 2+ and Tb 3+ can be accommodated simultaneously.…”

The need of new materials with desirable optical properties has become important in recent years. In particular, a need has emerged for compounds having better luminescence properties in various practical applications. The introduction of rare earth ions as activators improves the luminescence properties of the compounds considerably. Boron is one of the most abundant elements in nature. It readily combines with almost all other elements. In combination with oxygen; it forms borates comprised of various anions such as BO33−, B2O54−, etc. Apart from these simple borates, several complex compositions exist involving mixed anions as well as double metal borates, due to the three‐fold, or four‐fold coordination of borate atoms. Borates intrinsically possesses characteristics that are advantageous for optical materials, which include a wide transparency range, large electronic band gap, good thermal and chemical stability, low preparative temperature, optical stability with good nonlinear characteristics, and an exceptionally high optical damage threshold. The unique crystal structure of borates determines their enhanced ultraviolet light transparency, good nonlinearity, and relatively high resistance against laser‐induced damage. Some of these complex borates have interesting luminescence properties that are covered in this review. These include double borates containing rare earths RM3(BO3)4, pentaborates LaMgB5O10, M3R2(BO3)4, where M is an alkaline earth, mixed anion borates such as aluminoborate SrAl2B2O7, silicate‐borates such as pekovite, SrB2Si2O8, haloborates, M2B5O9X, where M is an alkaline earth and X is a halogen, phosphate borates, and MBPO5, where M is an alkaline earth. Phosphors based on these compositions find use in various applications such as fluorescence lamps, colour TVs, plasma display panels, high‐intensity discharge lamps based on xenon, optically pumped solid‐state lasers, eye‐safe lasers, and X‐ray imaging.

“…Because the absorbed nickel or yttrium became the active centre and a lot of crystal nuclei of the clusters formed, the coatings with large cluster density were retained up to the yttrium concentration of 6 mmol L − 1 in bath solution. 25 When further increasing Y 3+ to 8 mmol L − 1 , the size of the active centre decreased and the charged yttrium cations might form neutral molecule with , preventing its oxidation. 25,26 It was not enough to form large numbers of clusters of crystal nucleus.…”

NiYP alloy coatings were prepared on the surface of sintered NdFeB magnets by electroless composite plating. The effects of Y 3þ concentration on the deposition rate, surface morphologies, element contents and corrosion resistance were investigated. The results showed that the deposition rate of NiYP alloy coatings decreased with the increasing Y 3þ concentration. A thin NiYP film with adsorbed rare earth yttrium could be formed at higher concentration, which reduced the number of catalytic sites on the surface of intered NdFeB magnets. With the increase in Y 3þ concentration up to 6 mmol L 21 , the self-corrosion potential E corr of the electroless NiYP coatings in 3.5%NaCl solution increased from 2672 to 2513 mV, and the self-corrosion current density I corr decreased from 28.81 to 1.15 mA cm 22 . The mechanisms of corrosion resistance of the electroless NiYP coatings modified by Y 3þ addition were discussed.
