A display panel comprises a substrate, active switches and light-emitting diodes formed on the substrate. The active switches are disposed between the substrate and the light-emitting diodes. Each light-emitting diode comprises a first electrode, a second electrode, and a quantum dot luminescent layer. The quantum dot luminescent layer comprises a mesoporous frame. The mesoporous frame adopts a self-assembling form, the mesoporous frame serves as a main material, and quantum dots are disposed in the mesoporous frame. The first electrode, the quantum dot luminescent layer and the second electrode are stacked in order. Since the quantum dots are disposed in the mesoporous frame, the sizes of the quantum dots and the uniformity of their arrangement are adjusted and controlled, the light-emitting diodes with different luminous colors depending on the sizes of the quantum dots are then adjusted.

Tensile strained germanium is provided that can be sufficiently strained to provide a nearly direct band gap material or a direct band gap material. Compressively stressed or tensile stressed stressor materials in contact with germanium regions induce uniaxial or biaxial tensile strain in the germanium regions. Stressor materials may include silicon nitride or silicon germanium. The resulting strained germanium structure can be used to emit or detect photons including, for example, generating photons within a resonant cavity to provide a laser.

The application is related to a UV LED package structure for improving light extraction efficiency. An UV LED chip is set on a substrate with an anti-flare film for increasing upward light extraction to concentrate the emitted light by an optical element. Because no glue is filled between the UV LED chip and the optical element, it will be prevented the glue from spoiling and deteriorating by the UV light from the UV LED chip. Thereby, the UV LED package structure can prevent from the light performance reducing.
