Deep-Red CFQD®Quantum Dot Film
Model QDF-650


The Nanoco Deep-Red CFQD® Quantum Dot Film is the first quantum dot film released specifically for plant growth applications.  The film, when combined with blue and/or near-UV LEDs, provides the optimal spectra to encourage maximum chlorophyll absorption and promote healthy growing, while minimizing energy consumption and casting less heat than HPS bulbs and traditional LED units making it easy to control growing environments. Quantum dots also allow for additional, precise spectral tuning of the film depending on the specific plant being grown and can be tailored based on customer and application requirements.

Product Features and Benefits:

  • Deep-Red emission to stimulate optimal chlorophyll absorption (both chlorophyll A & B)
  • Uniform emission from quantum dot film allows for even distribution and full plant absorption.  No glare or hot spots.
  • Customizable size and shape available
  • Allows for the use of same fixture and blue/near-UV LEDs to be combined with different quantum dot films depending on plant to be grown
  • Reduced power consumption compared to HPS and traditional LED units
  • Ability to vary blue/red ratio per film
  • Reduced heat
  • Designed to work in conjunction with LED’s from 405nm – 455nm as required.


  • Horticultural lighting
