photoinduced electron sthanantaran

photoinduced electron transfer (pett) ack uttejit avastha electron hastaantaran prakriya haye jisake dwara ack uttejit electron koo daataa seey sweekaar karane vaale mein sthanantarit kiya jaataa haye. paltu janwar key kaaran ack avesh prithakkaran utpann hotaa haye, "i.ee."redox pratikriya uttejit avastha mein hoti haye (yeh ghatana dextor electron hastaantaran mein naheen dekhi jaati haye).
chaudaai.
aisee samagriyon mein ardhchaalak shamil hain jinhen kaee saur koshikaon kii tarah prakaash sakriya kiya jaa sakata haye, javic pranaaliyan jaise kii prakaash sanshleshan mein upayog kiye jaane vaale, aur upayukt avashoshan aur redox avasthaon vaale chhote anu shamil hain.
prakriya.
yeh varnan karna aam haye kii electron thoke padarthon mein electron pattiyon aur anuon mein electron kakshiyon key roop mein kahaan rahate hain. samichinta key liye nimnalikhit vivaran koo aanvik shabdon mein varnit kiya jaayega. jaba ack photon ack anu koo uttejit kartaa haye, tou ack bhoo-avastha kakshiya mein ack electron ack uchch oorjaa kakshiya key liye uttejit kiya jaa sakata haye. yeh uttejit avastha ack bhoo-avastha kakshiya mein ack rikt sthaan chhodati haye jise ack electron daataa dwara bharaa jaa sakata haye. yeh ack uchch oorjaa kakshiya mein ack electron kaa utpaadan kartaa haye jise ack electron sweekaarak koo daan kiya jaa sakata haye. inn mamalon mein ack photoexcited anu ack achche okseekaran agent yaa ack achche cumm karane vaale agent key roop mein kaary curr sakata haye.
donon pratikriyaon kaa antim parinam yeh haye kii ack electron ack kakshiya mein vitarit kiya jaataa haye joe oorjaa mein adhik hotaa haye jahaan vaha pahale rahata thaa. ardhchalakon key saath kaam karate samay ise aksar ack charge seey alag electron-chhed jodee key roop mein varnit kiya jaataa haye.
ack uchit electron daataa yaa sweekaarak kii anupasthiti mein aise anuon key liye samanya pratideepti utsarjan seey gujarna sambhav haye. electron sthanantaran photoquenching kaa ack roop haye.
baad kii prakriyaaen.
kaee prakaash-utpaadak pranaliyon mein iss avesh prithakkaran koo pee/aine junction seey judey cumm oorjaa conductor koo yaa ack electron parivahan shrinkhala mein electron key vitaran dwara gatij roop seey alag kiya jaataa haye. iss mamle mein kuchh oorjaa koo kaam karane key liye pakada jaa sakata haye. yadi electron gatij roop seey alag naheen haye tou ushmaagatiki apana adhikaar leey legaa aur utpaad ack dusare key saath pratikriya karke praarambhik samagri koo punah utpann karenge. iss prakriya koo punarsanyojan kahaa jaataa haye aur photon kii oorjaa ooshmaa key roop mein jaari kii jaati haye.
sambhaavit prerit photon utpaadan.
prakaash utsarjak diode (ell. ee. dee.) aur chemiluminascence dwara prakaash utsarjak electron hastaantaran kii vipareet prakriya pradarshit kii jaati haye, jahan sambhaavit pravanata kaa upayog uttejit avasthaon koo banaane key liye kiya jaataa haye joe prakaash utsarjan dwara kshay hoe jaate hain.
