Opportunities for permanent roles in a range of business sectors

Scientist or Senior Scientist: Nanocrystal Synthesis

Cambridge Photon Technology (CPT) is a spin-out company developing an exciting new technology that has arisen from breakthrough research at Cambridge University.  This technology has the potential to significantly increase the efficiency of conventional (silicon) solar panels.  CPT has identified an opportunity to develop a large new global business based on the technology.  Recently the company has attracted investment to accelerate progress and now wishes to expand its technical team.

The role holder will be a key member of the CPT team and will be embedded in the Physics Department at Cambridge University, working closely with both Company and University researchers, with a key focus on synthesising nanocrystals with improved photoluminescence quantum efficiency, lifetime and environmental stability in line with the company’s commercial applications in the field of photovoltaics.


The position is largely lab-based and, working closely with the technical team and collaborators, you will be responsible for:

  • Co-developing novel materials with energetic, spectral and functional characteristics for use in the company’s future breakthrough products.
  • Synthesis of nanocrystals with suitable ligand shells and related scale-up
  • Developing synthetic routes and recipes for improved performance (quantum efficiency, stability, ligand exchange) nanocrystal materials.
  • Performing rigorous optical and physical characterization (UV/Vis Absorption, Photoluminescence, PLQE, SEM/TEM, XRF etc.)
  • Reporting results at regular technical meetings and related planning, data analysis and record management.


With a PhD in Chemistry, Chemical Engineering or Materials Science focussed on inorganic colloid/nanoparticle synthesis, you will be able to demonstrate experience and expertise in the following areas:

  • Nanocrystal synthesis, core-shell nanocrystals, purification and control of nanocrystal ligand chemistry. (Essential)
  • Highly flexible and adaptable approach, applying both deep and broad relevant knowledge to successfully solving highly technical materials related challenges (Highly desirable)
  • Advanced optical/physical characterisation techniques for synthesised quantum dot materials related solutions and thin films (e.g. UVVis, PL, SEM/TEM, PLQE). (Essential)
  • Highly flexible and adaptable approach, applying both deep and broad relevant knowledge to successfully solving highly technical materials challenges (Highly desirable)
  • Ability to independently and effectively communicate and interact with team members and collaborators. (Essential)
  • Good record keeping and health and safety practices in an optics and chemistry focussed laboratory environments. (Essential)

In addition, knowledge and practical experience of the following would be advantageous:

  • Film coating via spin-coating or blade-coating techniques
  • Optoelectronic device fabrication and testing
  • Scripting of Matlab or Python data extraction and manipulation
  • Interfacing of equipment for automated sequence generation, e.g. with LabView

You will have excellent organisational capabilities, with the ability to prioritise, multitask and work to deadlines. You will have a strong team ethic, good verbal and written communication skills.  You will have a diligent attitude and be eager to learn and develop new skills. 

CPT can provide the successful candidate with the opportunity to contribute to the development of a business with the potential for truly global impact, both commercially and environmentally and the opportunity to grow with the organisation as technology goals are achieved.

CPT offers a competitive salary and benefits package. The role is full-time with a 37.5 hour working week, a 25-day holiday allowance and is based in Cambridge UK.
