We will be at MRS Fall 2018 in Boston, Massachusetts from the 25th to the 30th of November, 2018 at the Hynes Convention Center and Sheraton Boston Hotel.
The MRS meeting and exhibit provides a platform for the future of materials science, and offers networking opportunities to students, postdoctoral fellows, and Nobel and Kavli Prize Laureates, where they are able to exchange information and research with colleagues. The meeting will feature 9 symposium topics, including:
Our Americas Sales and Marketing Manager, will be in attendance throughout the course of the meeting, and will be exhibiting at booth 201, where we will have one of our FS5 Spectrofluorometers on display. Taking sensitivity to the next level, it is designed to meet the highest specifications in the research and analytical markets. A few key highlights of our FS5 include:

Our Application Scientist will be giving a poster presentation on the Photoluminescence Spectroscopy of Halide Perovskites.
Halide perovskites are a promising new class of semiconducting materials for a wide variety of optoelectronic applications, such as photovoltaics, light emitting diodes, lasers and optical sensing. They have received widespread attention due to their many attractive synthetic and photophysical properties, namely; solution processability, high tunability, long charge carrier lifetimes and high charge carrier mobilities. Photoluminescence spectroscopy is a powerful tool for the photophysical investigation and materials optimisation of halide perovskites.
Methyl ammonium lead iodide (MAPI) is one of the most efficient and widely investigated perovskite absorbers for photovoltaic cells. Using time-resolved photoluminescence, the charge carrier lifetime of MAPI was measured and was found to increase with the thermal annealing duration of the perovskite layer. In addition, temperature dependent photoluminescence spectroscopy was used to monitor the change in the perovskite bandgap with temperature and determine the orthorhombic to tetragonal and tetragonal to cubic phase transition temperatures.
Photoluminescence spectroscopy is particularly well suited for the study of perovskite materials for light emitting applications. Two dimensional perovskites are a promising material for the creation of single component white light source. We investigated the two dimensional white light emitter, α-(DMEN)PbBr4, using steady state photoluminescence to determine the chromaticity coordinates of the emission and time-resolved photoluminescence to probe the excited state lifetimes.
Using photoluminescence spectroscopy we have investigated the photophysics of a range of halide perovskite photovoltaic absorbers and light emitters and this will be discussed in fuller detail during the presentation.
