Thermoluminescence (TL) materials exhibit a wide range of applications in different areas such as personal dosimetry, environmental dosimetry, medical research etc.Doping of different rare earth impurities in different hosts is responsible for changing the properties of materials useful for various applications in different fields. These materials can be irradiated by different types of beams such as γ-rays, X-rays, electrons, neutrons etc. Various radiation regimes, as well as their dose-response range, play an important role in thermoluminescence dosimetry. Several TL materials, such as glass, microcrystalline, nanostructured inorganic materials and recently developed materials, are reviewed and described in this article.

In the modern era, growing number of indoor plants for various purposes, such as vegetation, flowering, and decorations, has increased over the traditional follow‐up trends for plantation. However, the indoor plantation requires different parameters for their growth; among these, light plays a significant role. In order to control the growth of plants using light‐emitting diodes, Mn‐doped oxide phosphors have emerged as promising candidates due to their broad and intense emission bands in the red and far‐red spectral range. In this review article, recent progress on Mn‐doped oxides for indoor plant growth has been reviewed. This review article is mainly divided into three parts. In the first part, different reaction conditions for the synthesis of Mn‐doped oxide phosphors are compared. In the second part, the luminescent and other photometric parameters of these are discussed. The influence of different co‐dopants on the luminescent characteristics has been elucidated in detail. The third part discusses the properties of light‐emitting diodes fabricated using these phosphors for plant growth. The present review article elucidates the synthesis parameters, luminescent properties, and light‐emitting diodes fabricated using Mn‐doped oxide materials for plant growth applications.

The phosphor converted w-LEDs gaincrucial attention in solid state lighting (SSL) for generation of illumination owing to their numerous meritorious advantages such as superior life time, excellent efficiency, compactness, reliability and power saving consumption as well as environmental friendly. The quality of w-LEDs in lighting and display is influence by host phosphorand the choice of activator. So greatlyattemptwere dedicated to developed inventiveuni-nucleiluminescent phosphor materials compose of chromatic stability, optimum CRI and low correlated color temperature. This review elaborate theintroduction ofEu3+rare earth activated red emitting phosphor assigned to 5D0→7FJ (J= 1,2,3,4) energy levelsand its fundamental merit for w-LEDs. This article represent the analyseofcombination of different types of Eu3+ activated luminescent materials by traditional and novel methods and its impact on photoluminescence for SSL.

Eu 3+ activated CaSiO 3 , (Ca, Ba) SiO 3 and (Ca, Sr) SiO 3 have been prepared by sol-gel technique. Residual solvent and organic contents in the gel were removed by firing at 100°C for 3-4 h at 300 and 600°C for 2 h. Small exothermic shoulder around 850 to 875°C, as observed in DTA curve, corresponds to crystallization temperature of the doped calcium silicate. Influence of firing temperature on the luminescence of Eu 3+ shows the maximum emission intensity in gel fired at 850°C. Photoluminescence emission peak is observed at 614 nm due to 5 D 0 → → 7 F 2 transition of Eu 3+ ion in (Ca, Ba) SiO 3 and (Ca, Sr) SiO 3 phosphors, when excited by 254 nm. The (Ca, Ba) SiO 3 material is proposed as an efficient red phosphor.
