与Ni/Al2O3和TiO2相比,TiO2−x/Ni-450催化剂表现出明显更长的弛豫过程(图2c-f),这表明电子从TiO2−x转移到Ni,导致TiO2−x的捕获过程更加困难。在TiO2−x/Ni-450催化剂的光子诱导电子激发和弛豫过程中(图2e),在520 nm激发处出现了~ 2170 cm−1和~ 2120 cm−1两个吸收峰,这两个吸收峰属于位...

Organic light-emitting diodes (OLEDs) must be engineered to circumvent the efficiency limit imposed by the 3:1 ratio of triplet to singlet exciton formation following electron-hole capture. Here we show the spin nature of luminescent radicals such as TTM
According to the PL spectra, type B QD-LEDs emitted a mixture of EL peaks centered at 622 nm and ~350–400 nm under the low applied bias voltage conditions, whose peaks are attributable to the radiative recombination at the QD layer and PVK film, respectively. The previous report of ...
That is, emission of white light can be obtained by mixture of light emitted from substances whose emission colors are complementary colors. The same can be applied to a light-emitting element having three light-emitting layers. For example, the light-emitting element as a whole can emit white...
