Textiles screen-printed with photochromic ethyl cellulose-spirooxazine composite nanoparticles [PDF]
, 2013 Photochromic compounds change colour on exposure to light, while the reversion may be attributable either to radiation or may be thermal. The use of photochromism on fabrics can provide new opportunities to develop smart textiles; for example, sensors ...

Photochromism of dihydroquinolines [PDF]
, 1970 Reversible photochromic reactions, in which absorption spectrum of chemical compound may be shifted by application of visible or ultraviolet light, and then returned to original state by heating, are observed for certain members of 1,2-dihydroquinoline ...

Importance of evaluating the intensity dependency of the quantum efficiency : impact on LEDs and persistent phosphors [PDF]
, 2018 The quantum efficiency is a key metric in lighting technology and for the quantification of luminescent processes, indicating how many photons are emitted with respect to the number of absorbed photons. Ideally, this value should approach unity to reduce
