Tunable luminescence and efficient energy transfer of Na2BaMgP2O8:Eu2+, Tb3+ phosphor for white light-emitting diodes

Effect of molybdenum on upconversion emission and temperature sensing properties in Na0.5Bi0.5TiO3:Er/Yb ceramics

“…Over the past decade, enormous interest in rare-earth (RE) ions doped materials has been gained owing to their wide applications in luminescent label for bioimaging, color displays, white lightemitting diodes, etc [1][2][3]. Some interesting phenomena, such as enhanced piezoelectricity, photoluminescence (PL), and upconversion (UC) emission, were observed in RE ions doped ferroelectric ceramics [4][5][6][7].…”

Near-Infrared Down-Conversion and Energy Transfer Mechanism of Ce3+-Yb3+Co-Doped Ba2Y(BO3)2Cl Phosphors

“…13 However, the emission of Ce 3+ , Eu 2+ and Bi 3+ are determined by the host structure, thus their emitting wavelength will varied in a wide range. [14][15][16] According to our previous results, the compound Ba 2 Y(BO 3 ) 2 Cl offers excellent chemical and physical stability and the emission of Ce 3+ in Ba 2 Y(BO 3 ) 2 Cl centered at about 415 nm with a broad strong absorption band ranging from 300 to 400 nm. 14 In this work, we demonstrate a near-infrared emission phosphor Ce 3+ , Yb 3+ co-doped Ba 2 Y(BO 3 ) 2 Cl with highly efficient energy z E-mail: guocf@nwu.edu.cn transfer (ET).…”

High Thermal Stability Apatite Phosphors Ca2La8(SiO4)6O2:Dy3+/Sm3+ for White Light Emission: Synthesis, Structure, Luminescence Properties and Energy Transfer

“…So far, there have been two kinds of method to get white light emission. One is that combination GaN/InGaN blue ships with YAG:Ce 3+ yellow emission phosphors, in which white light is composed of blue light and yellow light with cold color temperature owing to lack of red emission 4,5 . The other one is based on UV/n-UV chips triple color (red, green and blue) compounds white emission, of which color rendering index is better than the former, but trade-off luminescent efficiency, different decay situations, complex assembly processes and costs expensive are primary reasons for restricting its development 6,7 .…”
