Enhancement of red emission in Ba2Mg(BO3)2:Eu2+, Mn2+ phosphor under 365nm excitation

Structural and Mechanical Properties on Tb3+ Doped KBR Single Crystals

“…In recent years, the new lighting and display technology such as LEDs and FEDs have been proposed in industry, which result in the luminescence associated with Tb 3+ content in different host lattices has found applications [1][2][3][4][5][6] . Tb 3+ ion has the 4f 8 electron configuration undergoes 4f 5d transition and this electron excited state is 4f 7 5d…”

Electronic structure and Raman spectroscopy study of dibarium magnesium orthoborate, Ba2Mg(BO3)2

“…The crystal structure was first determined and reported by Akella and Keszler in 1995 [4]. Ba 2 Mg(BO 3 ) 2 shows good excitation characteristics from ultraviolent to red regions and has been reported to be a fascinating luminescence host for rareearth ions such as Ce 3+ , Eu 2+ , Eu 3+ , Pb 2+ and Sm 3+ [3][4][5][6][7][8][9][10][11][12][13][14][15]. Besides, Ba 2 Mg(BO 3 ) 2 has a large negative birefringence comparable to a-BBO with high transparency in the visible-light region due to the large energy difference between the non-bonding O lone pair electron state and BÀ ÀO bond state [16].…”
