Solution Combustion Synthesis and Energy Transfer in LaMgAl11O19:Tb3+/Sm3+ Tunable Phosphor
Volume 12, Issue 2 , February 2021, , Pages 1-6
Abstract
Tb 3+ /Sm 3+ single as well as co-doped LaMgAl11O19 (LMA) phosphors have been synthesized by a low-temperature solution combustion method. The X-ray diffraction pattern, photoluminescence properties and energy transfer (ET) processes between rare earth (RE) ions, were investigated in detail. The mechanism ... Read More)
Tb3+ Doped Sr2(BO3)Cl Green Emitting Phosphor For Solid State Lighting
Volume 5, Issue 10 , October 2014, , Pages 604-610
Abstract
In this paper we present luminescence results on Tb 3+ doped Sr2(BO3)Cl green phosphor. The vibrational properties of Sr2(BO3)Cl phosphor was studied by Fourier transform infrared spectroscopy. Photoluminescence studies have been carried out to understand the mechanism of excitation and the corresponding ...

Volume 5, Issue 7 , July 2014, , Pages 396-399
Abstract
Dy doped strontium aluminate phosphor (SrAl4O7:Dy(15% molar concentration)) was synthesized by combustion method using urea as a reducer at initiating temperature of 600oC. The absorption spectra shows the absorption edges at l = 242 nm, thus the band gap of 5.11 eV. The Thermoluminescence (TL) property ...

Volume 4, Issue 5 , May 2013, , Pages 363-367
Abstract
Anchor CaSO4: Dy, P is known for its dosimetric characteristics for a very long time now. In this work we have carried out a comparative study on TL intensity of CaSO4: Dy, P, Ce phosphors using two different wet chemical synthesis routes. Nobody seems to have reported this kind of study on CaSO4: Dy, ... Read MoreCombustion synthesis of X3.5Mg0.5Si3O8Cl4 (X3.5 = Sr,Ba):Eu2+ blue emitting phosphors
Volume 2, Issue 5 , November 2011, , Pages 327-330
Abstract
Eu 2+ luminescence in novel Sr3.5Mg0.5Si3O8Cl4 and Ba3.5Mg0.5Si3O8Cl4 phosphors is reported in this paper. These were synthesized by combustion method at 550 o C furnace temperature. The prepared phosphors shows PL emission spectra at 445 nm, due to 4f 6 5d 1 → 4f 7 transition of Eu 2+ ions by monitoring ...
