Abstract:
Phosphorescent material is widely used in light-emitting devices and in the monitoring of cell phenomena. Anthraquinone compounds (AQs), as important phosphorescent materials, have potential applications as emitters for highly efficient organic light-emitting diodes (OLEDs). Therefore, the accurate calculation of the phosphorescence energy of anthraquinone compounds is particularly important. This study mainly analyzes the phosphorescence energy calculation method of anthraquinone compounds.

AbstractBy incorporating ultrathin (<0.1 nm) green, yellow, and red phosphorescence layers with different sequence arrangements in a blue fluorescence layer, four unique and simplified fluorescence/phosphorescence (F/P) hybrid, white organic light-emitting diodes (WOLEDs) were obtained. All four devices realize good warm white light emission, with high color rending index (CRI) of >80, low correlated color temperature of <3600 K, and high color stability at a wide voltage range of 5 V–9 V.

Developing organic light-emitting diodes (OLEDs) as the next generation display devices is not only of industrial interest, but also a scientific challenge in and of itself that requires multi-disciplinary efforts to make the technology successful. Thermally activated delayed fluorescence (TADF) is a recent breakthrough in OLED technology whose prime value is to enable purely organic emitters to recruit the dark triplet excitons in the device, thus avoiding expensive and toxic rare metal based emitters.

Abstract:
This chapter introduces the design and fundamental concepts of organic light emitting diodes (OLEDs) and organic semiconductor lasers (OSLs). The chapter begins by describing device architectures used in fluorescent, phosphorescent, and thermally assisted delayed fluorescent (TADF) devices. Device characterization for both white and monochromatic OLEDs with application to displays and white illumination sources is discussed. OLED displays are compared with liquid crystal displays, and quantification of perceived color and luminosity is described. Materials and layer structures leading to high efficiency even at high brightness where exciton annihilation dominates, is followed by a discussion of methods used to efficiently outcouple light from substrate, waveguide, and surface plasmon modes. A discussion of reliability, with particular emphasis of the relatively short operational lifetime of blue phosphorescent and TADF devices, is provided. The last section is devoted to optically pumped OSLs, along with limitations encountered in achieving electrically pumped organic laser diodes.

Abstract:
In this chapter, we outline the basic theory and methodology for making time resolved fluorescence and phosphorescence measurements. We begin with a brief discussion of the intrinsic time dependence of fluorescence and phosphorescence decays, and also introduce several important photophysical concepts. Energy transfer measurements, which are important for determining molecular distances, are then addressed, followed by the convolution integral (which describes the luminescence decay that is actually observed in pulsed excitation experiments) and the relationships that are used to determine fluorescence lifetimes from phase/modulation data. Polarized fluorescence measurements, which are an important tool for following molecular motions, are then discussed, and the fluorescence portion of the chapter concludes with an overview of data analysis and brief descriptions of the instrumentation that is used in making time-resolved fluorescence measurements. The remainder of the chapter is then devoted to a discussion of phosphorescence spectroscopy. The intrinsic time dependence of fluorescence decays is derived in Section 3.3 of Chapter 2. There it is shown that if a population of excited singlet-state molecules is generated instantaneously, its size decreases exponentially with time, as does the intensity of the emitted photons. The fluorescence lifetime τS is typically used to describe the rate of decay, where τs-1 = kR + kNR + kISC + kPR and kR, kNR, kISC and kpR are the rate constants for the various parallel unimolecular de-excitation processes. If there are several non-interacting fluorophore species in solution, their excited states will decay independently and a sum of exponentials will be needed to describe how the sample’s fluorescence intensity decreases with time.

Abstract:
The use of fluorescent and phosphorescent optical probes for non-invasive chemical-based sensing in tissues is investigated using finite element computations. The results show that when the lifetime of the probe is significantly longer than the time associated with photon migration, the origin of the re-emitted signal becomes located closest to the surface. In order to probe more deeply, optical probes with lifetimes on the order of photo migration times are required. In such cases, deconvolution of the photon migration times from probe lifetimes are necessary for lifetime-based biochemical se
