Synthesis and photoluminescence characteristics of (Sr, Ca)3B2O6:Eu for application in white light-emitting diodes

Morphological and photoluminescence study of NaSrB5O9: Tb3+nanocrystalline phosphor

“…Inorganic borates doped with rare earth ions have found an important place in various research fields, moreover, due to their high optical applications, varied structural types, low synthesis temperatures, high chemical and thermal stability, and low cost and high luminescence efficiency. Many alkaline earth metal borates are reported for UV emissions used in medical applications [6] and various other applications [7][8][9][10][11][12]. They have a large band gap and covalent band energy.…”

Photoluminescence and thermoluminescence characteristics of Sr3B2O6:Eu2+ yellow phosphor

“…Sr 3 B 2 O 6 -doped Eu 2+ ions have been reported to be promising phosphors for wLEDs, because they have broad excitation and emission bands (3)(4)(5)(6). Sr 3 B 2 O 6 -doped Eu 2+ ions have been reported to be promising phosphors for wLEDs, because they have broad excitation and emission bands (3)(4)(5)(6).…”

“…In order to achieve a wLED, the first solution is using tri-colored phosphors (red, green and blue) excited via a near ultraviolet (near-UV, around 380-420 nm) chip. Another approach is a combination of a yellow phosphor together with a blue GaN chip (around 450-470 nm), which is commercially and widely used in modern society (2)(3)(4).…”

“…Recently, many yellow-emitting phosphors have been reported and Sr 3 B 2 O 6 :Eu 2+ is one of them. Sr 3 B 2 O 6 -doped Eu 2+ ions have been reported to be promising phosphors for wLEDs, because they have broad excitation and emission bands (3)(4)(5)(6). The photoluminescence excitation spectra of Sr 3 B 2 O 6 :Eu 2+ extend from 260 to 460 nm.…”
