Ar Ce un Eu joniem aktivētu oksifluorīdu stikla un stikla keramiku luminiscence

subject

description

Baltās gaismas diodes jeb LED lampas ir perspektīvi gaismas avoti. LED ir energoefektīvākas nekā kvēlspuldzes un videi draudzīgākas nekā fluorescentās lampas, taču to gaismas kvalitāte nav pietiekami augsta, salīdzinot augstajām izmaksām. Joprojām aktīvi norisinās jaunu redzamās gaismas luminoforu pētījumi zilām vai UV LED. Darbā sniegta īsa informācija par luminoforiem un gaismas kvalitāti, par oksifluorīdu stiklu un stikla keramiku, Ce3+ un Eu2+ aktivatora joniem. Darba praktiskajā daļā izgatavoti ar Ce un Eu aktivēti oksifluorīdu stiklu un stikla keramikas paraugi, iegūtas to luminiscences intensitātes un spektri. Iegūti arī atsevišķu paraugu ierosmes spektri un XRD spektri. Darbā secināts, ka visintensīvākā luminiscence ir ar Eu aktivētiem stikla keramikas paraugiem, kas ir salīdzināma ar komerciālās diodes luminofora intensitāti.
