Polymorphism in SmSc3(BO3)4: Crystal structure, luminescent and SHG properties

A new rare-earth oxyborate Ba3BiPbEuO(BO3)4and the luminescence properties of the Ba3BiPbY1−xEuxO(BO3)4phosphors

“…Inorganic borate phosphors, as an important family of luminescent materials, have attracted considerable interest owing to their relatively low synthetic temperature, excellent chemical and thermal stability, and high luminescent brightness. 23–27 In addition to these features, from the structural point of view, boron atoms may adopt either a 3-fold or 4-fold coordination with oxygen, appearing as isolated units or in combination, forming a great number of anionic groups, including rings, chains, sheets and networks, which can produce plenty of crystal field environments for luminescence host matrices. The introduction of lone pair-containing cations such as Bi 3+ and Pb 2+ , as well as lanthanide ions, into metal borate systems would dramatically increase the structural diversity and provide opportunities to find novel materials that can realize multicolor adjustable emissions in a single host.…”

“…Бораты, содержащие редкоземельные ионы, являются эффективными люминофорами и могут быть использованы в качестве материалов для цветных дисплеев, рентгенолюминофоров, светодиодных источников света [1][2][3][4][5]. Спектральные характеристики этих соединений определяются как электронной структурой оптически активных центров свечения, так и кристаллической структурой матрицы, в которой они находятся.…”

Growth and characterization of Na3R(BO3)2 (R = La–Gd) borates: crystal structure, high-temperature behavior, and optical properties

“…7–11 A large number of articles describe luminescent and nonlinear optical materials, which are devoted to the study of REE-containing and/or REE-doped borate compounds, showing the potential of their application in optoelectronic circuits and devices. 12–21 One of the most significant families of such compounds are represented by alkaline borates and REE-containing alkaline borates. 22–29…”
