Even small quantities of dopants, such as organic dyes and rare earth metals, can be introduced in the sol and end up uniformly dispersed in the final product.
42.
A 2nd order polynomial relationship between absorption and concentration is sometimes encountered for very large, complex molecules such as organic dyes ( Xylenol Orange or Neutral Red, for example ).
43.
The studies of photoconductive properties of organic dyes such as methylene blue were initiated only in the early 1960s owing to the discovery of the PV effect in these dyes.
44.
Experimental results suggest an in vivo detection sensitivity of 0.1-1 �M for organic dyes with a minimum detectable optical absorption coefficient of 0.1 1 cm-1, such as indocyanine green and Alexa fluochromes.
45.
Multiple-prism grating laser oscillators can be excited either electrically, as in the case of gas lasers and semiconductor lasers, or optically, as in the case of crystalline lasers and organic dye lasers.
46.
An apparel manufacturer, for example, might use a single mill product such as organic cotton cloth coupled with a few organic dyes and a few pieces of hardware such as zippers or buttons.
47.
The colors of light that can be produced efficiently by phosphors are limited, so many types of wire use an additional fluorescent organic dye in the clear PVC sleeve to produce the final result.
48.
It can be used to produce an organic dye ( known as Tamidye or TAMI dye ) which was developed at Moi University in Kenya under the direction of R . K . Mibey.
49.
The surgeon can see the glowing tumor, and use it as a guide for more accurate tumor removal . These nanoparticles are much brighter than organic dyes and only need one light source for excitation.
50.
His goal was to see if addition of the organic dye on the crystalline structure would induce " enhanced optical activity " ( rotation ) of light in the 500-600 nm absorption band on the otherwise optically inactive dye.
