Synthesis at room atmosphere conditions of phosphorescent emitter SrAlO:Eu,Dy

Synthesis and luminescence characterization of Eu3+‐doped Ca7Mg2(PO4)6 phosphor for eco‐friendly white light‐emitting diodes and thermoluminescence dosimetric applications

“…CIE coordinates were (0.638, 0.3608) and indicated that emission colour of the phosphors was located in the orange‐red region; the Ca 7 Mg 2 (PO 4 ) 6 :1mol%Eu 3+ phosphor has great potential as a red‐emitting phosphor. Colour purity of the specific dominant emission colour of a light source can be obtained using Schubert’s expression, given below (eqn 2) [ 33 ] : where (x, y) is the CIE chromaticity coordinate, (x i , y i ) is the coordinate of perfect white light, and (x d , y d ) is coordinate of the dominant wavelength. The dominant wavelength is a deviation from perfect white light, which corresponds to a point in the boundary of the curve and can be obtained using the intersection of the line that connects the centre with the colour point of the material.…”

Nanoscale Aluminate-Based Afterglow Materials from Byproducts of Aluminum–Water-Based Hydrogen Production for Anticounterfeiting and Latent Fingerprint Visualization

“…Figure a displays the CIE color coordinates ( x , y ) of SAO-R (0.71, 0.29), which can be regulated as red emission . Meanwhile, the SAO-G (0.26, 0.59) and SAO-B (0.17, 0.42), respectively, correspond to the green emission and blue emission . Besides, Figure b indicates the obvious difference in the afterglow performance of the above three nanophosphors.…”

“…56 Meanwhile, the SAO-G (0.26, 0.59) and SAO-B (0.17, 0.42), respectively, correspond to the green emission and blue emission. 57 Besides, Figure 5b indicates the obvious difference in the afterglow performance of the above three nanophosphors. The average afterglow time is ranked as follows: SAO-B (61 s) > SAO-G (11 s) > SAO-R (1.5 ms).…”

Synthesis, luminescence and persistent luminescence of europium-doped strontium aluminates

“…In 2015, Rojas-Hernandez et al [75] reported in detail the application of this method for the preparation of highly crystalline SA powder. They employed a eutectic mixture of NaCl-KCl salts medium to obtain nanosized crystals in only 1 h at 1173 K. Later in 2018 [76], this method was used once again for the preparation of SA nanoparticles. Although the luminescence emission intensity had improved compared to the former work, the afterglow duration was observed to be only 7 minutes.…”
