“…( 4f 9 ) shows three emission peaks (485nm, 570nm and a less intense red emission around 660nm) which can in principle lead to white emission, though with a poor color rendering [106]. The red emission of Sm 3+ ( 4f 5 ) is characterized by several emission peaks at approximately 560, 600, 650 and 700nm, in combination with a 4f-4f excitation peak around 405nm [107,108]. The quantum yield is seldom reported (which is often the case for the rare earth line emitters), although it is rather low in heavy metal tellurite glass [107].…”

Light emitting diodes (LEDs) are on the verge of a breakthrough in general lighting, due to their rapidly improving efficiency. Currently, white LEDs with high color rendering are mainly based on wavelength conversion by one or more phosphor materials. This Review first describes how to quantify the quality of a light source, discussing the color rendering index (CRI) and alternative color quality indices. Then, six main criteria are identified and discussed, which should be fulfilled by a phosphor candidate to be considered for actual application in LEDs. These criteria deal with the shape and position of the emission and the excitation spectra, the thermal quenching behavior, the quantum efficiency, the chemical and thermal stability and finally with the occurrence of saturation effects. Based on these criteria, the most common dopant ions (broad-band emitting Eu AbstractLight emitting diodes (LEDs) are on the verge of a breakthrough in general lighting, due to their rapidly improving efficiency.

“…And the curve was fitted with a single exponential function, which indicates that the Eu 3+ ions in Eu(IDTFBD) 3 phen molecules are located in the same parity sites. The luminescence quantum yield for the Eu 3+ complex was measured in solid state using an integrating sphere based on the method described by Lin [14]. And the luminescence quantum yield of the complex is φ = 0.16, which is good for a lanthanide organic complex.…”
