“…Therefore, host materials with Eu 2+ as an activator ion display tunable broad band emissions. 4,9,13 Borate-based hosts are considered among the most sought out hosts for Eu 2+ -based luminescent phosphors. It was found that in the SrB 4 O 7 (STB) lattice, a europium ion can be stabilized as Eu 2+ in an air atmosphere and the Eu 2+ -Eu 3+ oxidation is prevented by the surrounding nine BO 4 tetrahedra.…”

“…[ 15,16 ] For example, the most successful commercial photostimulators for storing phosphors are halides (e.g., BaFBr:Eu 2+ ) and sulfides (e.g., SrS:Eu 2+ , Sm 3+ , and CaS:Eu 2+ , Sm 3+ ), which show the strongest photostimulated luminescence (PSL) strength and the largest storage capacity. [ 17–19 ] In addition, some oxides (e.g., LiNbO 3 :RE, Sr 2 CaWO 6 :Mn, (Sr 1‐x Ba x )Si 2 O 2 N 2 :Eu/Yb,Dy, etc.) have been developed as optical information storage media in recent years.…”

With the fast‐growing amount of data, the state‐of‐the‐art optical data storage has become a front‐runner in the competing data storage technologies. However, two‐dimensional (2D) spatial resolution in the conventional optical data storage media has almost reached the limit. Herein, LiGa5O8:Cr3+ nanoparticles (NCs) precipitated in situ from a transparent medium are prepared. The transparent LiGa5O8:Cr3+ glass ceramics show excellent deep‐trap carriers storage ability under blue light irradiation and can realize the bit‐by‐bit optical data in 3D space for write‐in and read‐out in a photon trapping/detrapping mode. Moreover, this optical storage mechanism is also extended to 4D by realizing temperature optical encryption. Notably, the written information can still be clearly displayed even after being recorded for 200 days. This work enables 4D high‐precision storage of information and provides new insights into the design and fabrication of next‐generation storage materials.

“…Nowadays, one of the most widely used activator ions for phosphors for white LED's excited by blue/UV radiation is Eu 2+ due to its 4f-5d transition which ensures both wide emission and excitation bands, strongly depending on the local environment. In the last two years, publications on various hosts for Eu 2+ ions were reported [1][2][3][4][5][6][7], shifting the emission maxima from blue to red. Despite this fact, the well-known europium-doped SrSi 2 O 2 N 2 oxynitride phosphor still attracts significant attention, as one of the most suitable green phosphors for white LEDs, characterized by high quantum efficiency, chemical stability, high colour purity, limited thermal quenching and a broad excitation band [8][9][10][11].…”

Role of pressure in stabilization of oxynitride phosphor synthesis

The possibilities of improving the crystallization and optical properties of strontium europium oxonitridosilicate phosphor powders were discussed. Two different routes of synthesis were presented: traditional solid-state reaction method and gas pressure synthesis. It was proven that altering the partial pressure during the process of synthesis enhances crystallization of a desired single, triclinic SrSi2O2N2 phase. XANES measurements confirmed complete reduction of the trivalent europium activator ions in all of the tested materials. The photoluminescent properties were determined by emission, excitation and decay times measurements. CIE1931 colour points and luminous efficacy were calculated as well. Thermal quenching studies in the range of 0–225 °C confirmed good thermal stability of the investigated powders combined with excellent quantum efficiency at room temperature.
