On July 12, 2005, a Chinese porcelain piece titled "The large blue-and-white jar with motifs of Guiguzi going down the mountain, Yuan dynasty (1271–1368)", fetched a remarkable price of 14 million GBP at Christie's auction house in London. After factoring in the commission, this amounted...
The Blue and the Gray: Created by John Leekley. With Stacy Keach, John Hammond, Julia Duffy, Robin Gammell. America just before and during the Civil War, as seen through the eyes of an artist correspondent.
A broadband blue-emitting Sr_(1-x)Ca_(x)Lu_(2)O_(4):Ce^(3+)(x=0-0.2) phospho rs were synthesized,which can be used for near-UV pumped white light-emitting diodes(w-LEDs).The crystal structures,photoluminescence pro perties,external quantum efficiency,the rmal stability and application...
(518 ± 32 nm; 0.16, 0.72), red (631 ± 16 nm; 0.70, 0.30) and white (peaks 446 nm and 560 nm; 0.33, 0.34). Due to the coronavirus pandemic, an alternative setup with two separate laboratories had to be used. For details, please see the ‘Deviations from ...
The efficiency and stability of red and green quantum-dot light-emitting diodes have already met the requirements for commercialization in displays. However, the poor stability of the blue ones, particularly pure blue color, is hindering the commercializ
Japanese blue-and-white porcelain was developed in the Hizen area on Kyushu during the early seventeenth century and quickly shared the overseas markets wi
There is provided a blue excited yellow fluorescent material that shows a broad light emitting spectrum ranging from green components to red components, is easy to control color tones, has high color rendering properties, and can provide white light close to natural light (sunlight), by combining...
Pr3+-doped Li2SrSiO4 red phosphor for white LEDs Novel red phosphors, Li 2Sr 1–1.5 xSiO 4: xPr 3+ ( x=0.002, 0.003, 0.004, 0.005, 0.006 and 0.008), were synthesized by conventional solid state reaction a... 饶阳,胡小野,刘涛,... - 《Journal of Rare Earths》 被引量: 107发表...
White thin-film flip-chip LEDs with uniform color temperature using laser lift-off and conformal phosphor coating technologies We fabricated a phosphor-conversion white light emitting diode (PC-WLED) using a thin-film flip-chip GaN LED with a roughened u-GaN surface (TFFC-SR-LED) t... Huan...
