Abstract
In chapter one, the basis and fundamentals of photochemistry were introduced. This demonstrated the origin and mechanism of light emitting materials, especially for applications of organic light emitting diodes. The development of osmium metal complex for blue and red OLED applications was also illustrated in this chapter. In chapter two, we will measure and discuss the photophysical properties of the osmium metal complexes containing 2-pyridyltriazole and chelating phosphine. From the measurements, we can get the phosphorescence spectra, lifetime, quantum yield and radiative decay constant. Further discussions are the effect of different electron donating/withdrawing group. It shows that these complexes are very suitable for red emitting materials. In chapter three, the development and applications are shown here. The main focus is on the modern techniques, including the laser scanning confocal microscopy, atomic force microscopy, scanning near-field microscopy and multi-photon microscopy. Due to the non-invasive property, optical microscopy plays an important role in biomedicine and life science. It is also widely used for nanoscience and nanotechnology. The last chapter will demonstrate the various types of measurements and applications, including the micro-PL, second harmonic generation and micro-Raman.
