Publication date: Available online 14 May 2019Source: Progress in Materials ScienceAuthor(s): Zhi Chen, Guoping Dong, Hanwei Gao, Jianrong QiuAbstractProbing the nature of two-/multi-wavelength light excitation effects in optical materials, such as its mechanisms, materials composition, opt-electronic behaviors, is crucial for observing photophysical and photochemical performances for their applications. Recently this research area has stimulated extensive attention owing to its remarkable optical performances; capable of tunable fluorescence emission, tailorable photochemical reaction, controllable electrons population, and driving novel photophysical and photochemical phenomena, which are promising for emerging applications in broad areas of spectroscopy, photophysics, photochemistry, opt-electronics, biophysics, environment, and materials science. In this work, we will review recent progresses in the interdisciplinary studies on photoluminescence mechanisms, emitting centers, host materials system, optical setups and characterization techniques, and application fields for the optical materials by two-/multi-wavelength light excitation effects. In the first part, we will introduce latest progress of two-/multi-wavelength light excitation effects in optical materials from fundamentals to applications. In the second part, we will present dominating two-/multi-wavelength excited photoluminescence mechanisms, including excited state absorption, stimulated emission depletion (ST...
