Upconversion Mechanisms: Understanding The Different Techniques Used
Upconversion mechanisms are crucial in understanding how the process of upconversion works. Upconversion is a phenomenon where low-energy photons are converted into higher-energy photons through various mechanisms. Understanding these techniques is essential to grasp the concept of upconversion fully.
One widely used technique is called sequential two-photon absorption (TPA). This mechanism involves absorption of two low-energy photons, which combine their energies to create one higher-energy photon. This process occurs in rare-earth doped materials, such as yttrium aluminum garnet (YAG) crystals, where energy levels of dopant ions are engineered to facilitate TPA.
Another mechanism, called energy transfer upconversion (ETU), involves the transfer of energy between different types of dopant ions within a material. When a high-energy donor ion transfers its energy to a low-energy acceptor ion, the acceptor ion emits a photon with higher energy than the original excitation. ETU is commonly used in lanthanide-based materials.
Other upconversion mechanisms, such as photon avalanche and cooperative upconversion, also contribute to the overall upconversion process.
