Product Name: EviDot Semiconductor Nanocrystals
Product Description
EviDots are an exciting new semiconductor nanocrystal quantum dot technology
developed by Evident Technologies. Ideal for nanotechnology researchers and
product developers, EviDots provide scientists with a variety of nanocrystals
suspended in a solution for experimentation and applications development.
About Evident's Semiconductor Nanocrystal Quantum Dots
EviDots are manufactured quantum dots that range in size from 2-10 nm and
contain less than 1,000 atoms. Each EviDot type is precisely composed of the
same material but exhibits different emission properties based upon the size of
the quantum dot.
EviDots produce high quantum yields with intense fluorescent brightness at
targeted peak wavelengths. Available in a wide range of colors, EviDots exhibit
a broad excitation spectrum and can be excited by light at any wavelength
shorter than the EviDot's stated emission peak. This makes possible simultaneous
detection of nanocrystals with different emission peaks, imaging and
quantification. EviDots are available for applications ranging in wavelength
from 490-2000 nm.
EviDot Applications
EviDot semiconductor nanocrystals can be used to enhance and expand applications
in photonics, biological and nanotechnology optics.
- Biology -- fluorescent tags to measure and quantify biological
phenomena
- Precision light calibration -- a source of precision wavelength
materials
- Semiconductors -- "designer atoms" that allow control of the
bandgap through material and composition sizes
- LEDs -- tunable colors for light-emitting diodes
- Photovoltaic Solar Cells -- low-cost, high-efficiency devices
- Optical Transistors -- ultra-fast switching devices under 1

Ocean Optics Systems for Use with Evidots
Ocean Optics makes available numerous light sources and filters that can be used
to excite EviDot nanocrystals. For instance, the LS-450 LED Excitation source
can be used with an LED-380 bulb to produce light at 380 nm and excite the full
range of EviDots. For broadband light sources that produce energy above the
EviDot's peak emission wavelength, an Ocean Optics Linear Variable Filter (LVF)
is suggested. An LVF effectively blocks or passes light between 300-700 nm.
To assemble a complete fluorescence spectrophotometric system for use with
EviDots, Ocean Optics recommends its USB4000-FL Spectrometer and a USB-LS-450
Pulsed LED excitation source.
