Luminescence of YAl3 (BO3)4: Eu2+, Dy3+ phosphor and its luminescence decay characteristics

Abstract: Eu 2+ , Dy 3+ co-doped YAl 3 (BO 3 ) 4 phosphors are synthesized by sol-gel method. The phosphors show prominent blue luminescence due to the 4f 7 -4f 6 5d transition of Eu 2+ . The emission intensity is greatly improved when Dy 3+ is doped into the YAl 3 (BO 3 ) 4 :Eu 2+ system. The 1% Dy 3+ in Eu 2+ , Dy 3+ co-doped YAl 3 (BO 3 ) 4 phosphors is the optimum doping concentration. The luminescence decay characteristics of the samples have also been investigated, exhibiting the decay times of approximately 0.1 μ… Show more

“…The luminescence properties of lanthanide ions or transition metal ions doped in YAl 3 (BO 3 ) 4 phosphors have been studied many times, such as Tb 3+ , Sm 3+ , and Cr 3+ , parts of them show promising properties as laser or LEDs materials. 21,22 Some potential applications of phosphors have been predicted using the CALYPSO structure search method, such as YAB: Nd and YAB: Tm, which are good laser materials. 21,22 Some potential applications of phosphors have been predicted using the CALYPSO structure search method, such as YAB: Nd and YAB: Tm, which are good laser materials.…”

“…[12][13][14][15][16][17][18][19][20] And Gd 3+ , Eu 2+ , Dy 3+ -doped YAl 3 (BO 3 ) 4 phosphors show potential application value in PDP. 21,22 Some potential applications of phosphors have been predicted using the CALYPSO structure search method, such as YAB: Nd and YAB: Tm, which are good laser materials. Although this method is accurate, more experimental data about lanthanides-doped YAB are still needed.…”
