Perovskite lasers

Perovskites are materials that share a crystal structure similar to the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3).

Depending on which atoms/molecules are used in the structure, perovskites can possess an impressive array of interesting properties including superconductivity, ferroelectricity, charge ordering, spin dependent transport and much more. Perovskites therefore hold exciting opportunities for physicists, chemists and material scientists.

Lasers are devices that stimulate atoms or molecules to emit light at particular wavelengths and amplify that light, typically producing a very narrow beam of radiation. The emission usually focuses on an extremely limited range of visible, infrared, or ultraviolet wavelengths.Laser is an acronym for “light amplification by the stimulated emission of radiation”. Lasers are used in extremely diverse industries and applications, like optical disk drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optics, laser surgery and other medical applications, military and law enforcement devices and much more.

As direct bandgap semiconductors, perovskites exhibit the unique optical properties of bandgap tunability, charge-carrier mobility, defect tolerance, photoluminescence quantum efficiency and power conversion efficiency. These properties make them promising light-emitting materials for high optical gain, low-threshold and multicolor laser applications. The fact that they can be fabricated from low-cost precursors via simple processes makes them attractive as well.

Lower dimensionality perovskite materials, like nanoplatelets, dots, disks, wires etc., can be tailored to be highly desirable for controlled lasing because of their optical cavities and feedback architectures.

Despite their promising features, there are several challenges, for example low exciton binding energy, environmental stability, and formation of trap states at the vicinity of grain interfaces, that need to be addressed when considering perovskite use in lasers. In that respect, 2D perovskites and triple/mixed cation perovskites appear to have potential.

Applications of perovskite materials in the display industry

This article was extracted from the Perovskite for Displays market report.

Given perovskites materials' unique optical properties, these materials are being intensively researched for both photovoltaic and display applications (as well as several others). In this article we will take a look into the possible application areas in the display industry that can benefit from perovskite materials.

Perovskite QDs

Perovskite-based QDs (PerQDs) are considered a viable Cd-free alternative for display applications, with high PL quantum yields, wide wavelength tunability and ultra-narrow band emission. The main advantages of PerQDs are:

  • Low cost
  • High performance
  • RoHS compliance (despite the lead content)

Project HIPER-LASE sets out to explore perovskite lasers

The German Research Foundation (DFG) is funding a new project, kicked off on October 5, 2021, called 'project HIPER-LASE'. The new project will explore the potential of perovskite semiconductors for realizing an on-chip electrically pumped laser.

Integrated photonic-circuits could trigger the next technological revolution in microelectronics. The prerequisite, however, is the availability of a cost-effective and scalable manufacturing technology. An excellent candidate for this task is the photonics platform based on silicon/silicon-nitride. What is still missing though, is an integrable laser source. In the DFG-funded project HIPER-LASE, AMO and partners RWTH Aachen University, the University of Wuppertal and the University of Siegen will explore the potential of perovskite semiconductors for realizing an on-chip electrically pumped laser.

Researchers demonstrate broad-band lead halide perovskite quantum dot single-mode lasers

A research team from the Shanghai Institute of Optics and Fine Mechanics has recently demonstrated perovskite CQDs (colloidal quantum dots) single-mode laser with good performance across the entire visible spectra range.

In this study, a composited microcavity was obtained through the conformal deposition of cesium lead halide perovskite (LHP) CQDs on a high quality individual sub-micron ZnO rod by dip-coating self-assembled techniques. A single-mode lasing with high quality factor and low threshold was obtained.
