Energy transfer and colour tunability in UV light induced Tm3+/Tb3+/Eu3+: ZnB glasses generating white light emission

Fast and simultaneous doping of Sr0.9−−−Ca0.1In2O4:(xEu3+, yTm3+, zTb3+) superstructure by ultrasonic spray pyrolysis

“…This behavior is associated to the cross-relaxation energy transfer between RE ions which are very close at a distance determined as critical distance (CD). In this condition, the activating ions (A) which are constituted by RE ions interact with each other so that non-radiative transitions are favored due to better non-radiative coupling between the ions [54]. The excitation energy is transferred randomly from one ion to another, leading to the concentration quenching and consequently suppression in photoluminescence.…”

Fabrication, tunable fluorescence emission and energy transfer of Tm3+‐Dy3+ co‐activated P2O5–B2O3–SrO–K2O glasses

“…Fluorescence glasses doped with RE ions capture researchers' attention due to high transparency, easy preparation, strong mechanical hardness, excellent moisture resistance, thermal stabilities . They can emit multi‐colors or white light by doping different rear‐earth (RE) under the appropriate excited wavelength due to the existence of the efficient 4f‐4f and 4f‐5d electronic transitions of RE ions . Many RE ions‐doped glasses have been reported.…”

“…Many RE ions‐doped glasses have been reported. For example, Dy 3+ ions doped lithium alumino‐borate glass, Dy 3+ /Tb 3+ ions co‐doped borate glass, Tm 3+ /Tb 3+ /Eu 3+ (Sm 3+ ) tri‐doped zinc borate/phosphate glass . We can avoid the use of organic polymer binders through the fabrication design.…”

For example, Dy 3+ ions doped lithium alumino-borate glass, 11 Dy 3+ /Tb 3+ ions co-doped borate glass, 12 Tm 3+ /Tb 3+ / Eu 3+ (Sm 3+ ) tri-doped zinc borate/phosphate glass.…”

White light emission from single-phase Y2MoO6: xPr3+ (x = 1, 2, 3 and 4 mol%) phosphor

“…In this situation, single-phase phosphorus, which emerges as white emitters, presents luminous efficiency, excellent CRI, adjustable temperature and purity in its chromaticity coordinates [12]. Naresh et al [13] used zinc borate matrix combined with Tm 3+ , Tb 3+ and Eu 3+ ions under ultraviolet light excitation to generate white light emission, obtaining satisfactory results regarding purity, reproducibility and proximity properties of the standard white light conditions. Their study was based on the evaluation of energy transfers among doping elements.…”
