Asalamualykum sir congratulations to you for getting selected .I am always thankfull to you your vedios helped me a lot when i was very needy thanks thanks thanks.....bro may Almighty Allah help you in every field of life and make you successfull in aakhirah
in 3rd step the electrons are trapped in F - centers,for lumninsce to happen we need to bring electron back into valence band That means we need to snatch or decrease energy of electron to drop into valence band Then why we give extra energy to electron to excite it again and put it into conduction band why not directly from f centers to valence band And if it is nessary to excite electron from f centers so that it reaches conduction band ,then after loosing energy this electron again falls on f centres and gets trapped rather than valance band what is the logic in this sir
Thank you Sir for this amazing lecture 😊

what is the logic in this sir
Sir Answer??
Why electron fall down from conduction band to F-centre?
To Come Back to the ground state....where they r more stable
@@RadiographyMadeEasy thank you sir
