A phenomenon of light emission by certain materials after exposure to an excitation source is called luminescence. Long persistent phosphors are those having very long afterglow emission or phosphorescence, in some cases even longer than a whole day, and a large application fields. Afterglow is caused by trapped electrons or holes produced during the excitation. The long persistent phosphorescence mechanism of the inorganic phosphors activated by rare earth ions have been attempted to be explained by many researchers. During the last decade, the researches on the development of new persistent phosphors and the improvement of their life time have been considerably conducted. In the present study, the effects of praseodymium oxide (Pr6O11) doping in SrAl2O4:Eu2+, Dy3+, Y3+phosphor on the luminescence efficiency and phosphorescence properties were investigated. Additionally, after the production, the possible application of the most suitable pigment developed during the study onto artistic glasses was searched.

 

Bir uyarım kaynağına maruz bırakılan bazı malzemelerin kaynak uzaklaştırıldıktan sonra da ışık yayınımına devam etmeleri olayına lüminesans adı verilmektedir. Uzun ışıldama süreli fosforlar, çok geniş bir zaman diliminde, hatta bazen bütün bir gün boyunca bu yayınımı yapabilen ve fosforesans özellik sergileyen, oldukça geniş uygulama alanına sahip malzemelerdir. Işıldamada kalıcılık, uyarım süresince tuzaklanan elektronlar veya meydana gelen boşluklar neticesinde ortaya çıkmaktadır. Nadir toprak iyonları tarafından aktive edilen inorganik fosforlarda uzun süre kalıcı fosforesans mekanizması birçok araştırmacı tarafından açıklanmaya çalışılmıştır. Son 10 yılda araştırmacılar yeni kalıcı fosforların geliştirilmesi ve sönümlenme ömürlerinin iyileştirilmesi üzerine başarılı çalışmalar gerçekleştirmişlerdir. Bu araştırmada, SrAlO4:Eu+2, Dy+3, Y+3 sistemindeki fosfora prasedmiyum oksit (Pr6O11) katkılamasının lüminesans verimine ve fosforesans özelliklere etkileri araştırılmıştır. Ayrıca, optimum özelliklere sahip şekilde geliştirilen fosforesans pigmentlerin sanatsal camlarda uygulanması üzerine çalışmalar yapılmıştır
