Microstructures of pulsed laser deposited Eu doped Y2O3 luminescent films on Si(001) substrates

Production, characterization, and luminescent properties of Eu3+ doped yttrium niobate–tantalate films

“…Over the last few years, a number of researches have been carried out on the growth and characterization of luminescent thin films of YTNO. When compared to the powders, thin film phosphors present a few advantages because of their good luminescence characteristics, higher image resolution from small grains, better thermal stability, and good adhesion to the substrate [20][21][22][23][24][25]. Various chemical and physical methods are utilized for the deposition of luminescent thin films.…”

Influence of annealing temperature on microstructure and luminescent properties of Y2O3: Eu3+deposited quartz fibre

“…3 Among oxide based phosphor thin films, Y 2 O 3 : Eu 3þ thin film is one of the excellent luminescent materials because of its highly luminescent efficiency, 4 and it can be grown by different deposition methods, such as electron beam evaporation (EBE), 1,2,5 pulsed laser deposition [6][7][8] and radio frequency sputtering. 9 Numerous researchers have dedicated their efforts to investigate microstructure and luminescent properties of the thin films; however, most of Y 2 O 3 : Eu 3þ phosphors were deposited on rigid substrates, such as glass, sapphire and silicon.…”

Development of luminescent europium-based phosphor films

“…Firstly, Y 2 O 3 has low phonon energy. The highest phonon energy is about 600cm -1 and the most effective phonon is between 430cm -1 and 550cm -1 [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], . The low phonon energy makes the radiative relaxation more possible and thus enables higher emission efficiency.…”

“…The critical transfer distance (R c ) between the two Eu 3+ dopants can be approximated to twice the radius of a sphere [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], , that is:…”

“…The corresponding UV random laser pumped red emission intensity at 611nm of the spectra has previously been shown at the vertical left axis in Figure 6-10. place between the 5 D 0 and the 7 F J (J=0-6) states because of the larger gap [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The radiation is dominated by the red emission peak at 611nm, which arises from the 5 D 0 -7 F 2 emission transition.…”
