There is an enormous demand for optical sensors in many areas, such as the environmental monitoring, industrial and food processing, healthcare, biomedical technology, and clinical analysis, where high sensitivity and ease of operation are two main issues (Shi et al., 2004; Jeronimo et al., 2007). Fluorescence technique can easily fulfill both requirements and has been widely applied in the fields of chemical sensing and biosensing (Jiang and Guo, 2004; Prodi, 2005; Lim and Lippard, 2007). In the design of fluorescence-based sensors, the fluorescence probes remain a key determinant to the future success of the sensor. Therefore, the development of fluorescence probes has been a long-term and attractive topic among the scientists (Callan et al., 2005; Demchenko, 2005). In this regard, many kinds of fluorophores have been developed, and already been applied in the sensors design. Unfortunately, the performance of these established fluorescent sensors are greatly limited by using the conventional fluorescence probes. For instance, organic fluorophores, which are most commonly used in fluorescence technique, suffer from low brightness and poor photostability, which lead to reduced sensitivity and stability of the sensor (Zhou and Zhou, 2004; [Demchenko, 2005; Prodi, 2005).] There is an enormous demand for optical sensors in many areas, such as the environmental monitoring, industrial and food processing, healthcare, biomedical technology, and clinical analysis, where high sensitivity and ease of operation are two main issues (Shi et al., 2004; Jeronimo et al., 2007).

In addition, organic fluorophores tend to have small Stokes shifts, thus limiting their utility in the fields, such as ratiometric measurements and fluorescence resonance energy transfer (FRET)- based detection (Demchenko, 2005). Compared with conventional organic fluorophores, the recently developed semiconductor quantum dots show great promise as the fluorescence probes due to their improved photophysical properties, including high quantum yield, size-tunable narrow emissions and minimal photobleaching (Costa-Fernaˇındez et al., 2006; Somers et al., 2007). However, these nanocrystalline materials still suffer from several issues, such as the harsh and toxic conditions in the synthesis, large physical size, strong non-molecular low-power fluorescence intermittency, which also limit their further application in fluorescence sensing research (Verberk et al., 2002; Derfus et al., 2004; Vosch et al., 2007). Therefore, the development of new fluorophores that can challenge the above problems is of great importance for both fluorescence sensing and other fluorescence-based applications like fluorescence imaging (Rao et al., 2007).
