“…However, one of the most interesting characteristics of graphene is the ability to support plasmonic transverse magnetic (TM) modes, with less losses (ohmic and radioactive) than in metals, which makes graphene a promising material for applications in plasmonic devices [4, 6]. In addition, plasmonic devices that use noble metals have resonance in the spectrum above the infrared, at high optical frequencies [7]. In contrast, graphene‐based devices can operate in the Terahertz range below the infrared, enabling new possibilities at relatively lower frequencies, and therefore with smaller loss [8].…”

“…Due to the efficiency in lighting and energy-saving, the diodes with light radiating ability called LEDs has soon recognized as potential lighting method. The applications of LEDs are spread out in many different fields from general usage of street lighting, back-lighting to more advanced utilization in medical and automobile [1][2][3]. To produce white light, the most common approach is to apply the combination of chromatic lights which yielded from the blue LED chip and the phosphor that ejects light downward.…”

The angular color uniformity (ACU) with the ability to evaluate chromatic performance of WLED has become an important target to achieve in producing higher-quality WLEDs. This paper studies the ACU enhancing effects of novel triple-phosphor configuration in lighting devices with remote phosphor structure. Moreover, the optical influences of remote phosphor structure with three phosphor layers (TL) on WLEDs properties are calculated and compared to the dual-layer (DL) one for reference. The experiments are applied to devices at 5 distinct correlated color temperature ranging from 5600-8500 K. The results presented that DL structure attains better color rendering index (CRI) than the TL one. Meanwhile, in terms of color quality scales (CQS), TL model shows higher values at all ACCTs, compared to the DL. Moreover, the luminous flux of DL configuration is lower than that of TL structure. In addition, the diversion of color temperature depicts as D-CCT in TL structure is much better than the value in DL structure, especially at high ACCT as 8500 K, which means TL is good for chromatic uniformity of high ACCTs WLEDs. These results proved that the triple-layer structure is superior and more effective to apply for acquiring the enhancement of WLEDs package.
